Cruise Ship Passenger Capacity

View cruise ship ratings and learn what is average/normal and max cruise ship passenger capacity. Cruise ships capacity (passengers and crew/hotel staff) and space ratios of the world's most famous ships are sorted alphabetically by the names of their owners (companies, lines, and operators) according to the official cruise ship data.

Most online travel media publish ship ratings based on onboard amenities (dining/entertainment), itineraries/destinations, special/unique facilities, and experiences. Some ratings are based on website visitors' feedbacks and conducted polls. However, while the latter ratings could by easily manipulated, "expert review" based ratings could be only suggestive as top-rated will be always the largest liners and the  newest vessels .

Cruise Ship Capacity

The "full" cruise ship passenger capacity is based on double occupancy (2 guests per cabin). The cabin's capacity varies according to stateroom's type, category, and also by line and ship. A standard passenger ship cabin usually accommodates 2 or 3 guests, but there are some "smaller" and "bigger" exceptions.

Our survey also includes smaller ships (under 500 passengers), and some ships are intentionally omitted from the big table to be included in the small one (about passenger capacity of top luxury cruise ships, with emphasis made on their highest guests-to-crew ratio. If searching for a particular vessel, use the Ctrl+F key combination and type the name in the search box. Good to know things:

• Ships will sail at varying capacities depending on itinerary and season.
• The average cruise ship passenger capacity is around 3,000 guests for ocean liners and around 150 guests for bigger river cruise ships.
• The largest cruise ship passenger capacity is 5,412 (at double occupancy) and 6,318 max capacity if all berths are occupied. And, of course, these big numbers are part of the specifications of the first in the  list of the biggest cruise ships in the world  - the Oasis ship of Royal Caribbean International.
• Single cruise cabins (called also "studios", or "solo cabins"), though rarely available, offer some of the cheapest rates for solo travelers by avoiding the double occupancy policy of all the major cruise ship companies, with the range of single supplement rates being between 50 and 100% (depending on line and ship).
• Family suite cruise accommodations generally have the biggest passenger capacity (up to 6 guests) and are some of the most expensive cabin categories (again, not available on all ships). Cheap suites are available on most Carnival, Royal Caribbean, MSC, and Costa ships.

Max (largest) passenger capacity of a cruise ship would signify this ideal financial situation, when all the berths, plus all upper and lower bunks, "Pullman" beds and single and double sofa beds (available in types and numbers according to the ship's cabin grades) are all occupied by the most numerous crowd the ship can ever gather on board. However, on most of the sailings, even the full-ship capacity (at double occupancy level) is not reached. This automatically opens the "big ships doors" for great deals, like kids sail for free, buy one get one free, free cabin upgrades, bonus amenities, and also huge price discounts on luxury cruise deals. For more info, you can read our survey on unsold cruise cabins/cheap cruise upgrades .

Cruise passengers-to-space ratio

The ship's "space ratio" (by definition) is the enclosed space (measured in ft3/cubic feet) per passenger. A ship of 45,000 GT (gross tonnage) with capacity 1,000 passengers will have a space ratio 45 (or 45ft3=45000/1000). So if your ship has generally smaller cabins but very large public spaces, she will have a higher space ratio, and the higher the space ratio number, the more guests will enjoy a sense of spaciousness on board.

Cruise Ship Ratings

0 (or no Stars) doesn't mean the ship is the worst ever, but not yet rated.

"Specialty" means usually a smaller ship offering deals on adventure or expedition cruises. Emphasis on itinerary/destination and unique experiences rather than onboard services/amenities/activities. Cabins are modest (as size and amenities), but also comfortable.

3 Stars mean "Contemporary" and big resort-like experiences on bigger ships with a multi-generational clientele, a huge variety of family and kids programs, at least 2 swimming pools, huge fitness/spa centers, distinct nightlife (clubs, a casino, deck parties), several dining options. Cabins range from cozy Inside to large family suites and many connecting/adjoining rooms. Itineraries from 3 to 7-night in length (repeating, round-trip) leaving from big and popular ports.

4 Stars mean a "Premium" product, medium-sized ships with higher guest-to-crew ratios compared to similar-sized mainstream ships. The onboard experience - fewer kids, larger than average cabins with upgraded (luxurious) amenities, high-level of service, dining, and entertainment, extensive enrichment programs, a luxury spa, longer itineraries (from 7 to 14 and even 21-night in length).

5 Stars mean a "Deluxe" product, from medium-size to small cruise ships with deluxe staterooms, bedding and cabin amenities, impeccable service, multiple specialties (gourmet) dining options, also less entertainment and onboard activities. The itinerary is mostly port-intensive, and longer than 10 nights, with deals on back-to-back cruises .

6 Stars mean "Best Luxury" on small ships, intimate cruising experiences, highest guest-to-crew ratios (fewer guests). These are mostly ships with all-inclusive cruise deals - gratuities and beverages (often alcohol) and gourmet (specialty restaurant) dining are all included in the fares (often with shore excursions and tours), spacious staterooms and public spaces, the highest level of service. Many of these are all-suite ships (with different category suites). Port-intensive itineraries and exotic destinations, often offering deals on Around the World Cruises .

All cruise ship ratings are based on CLIA (Cruise Lines International Association) categorizations, and reviews from "WMPH Vacations" (iCruise, AlaskaCruises, EuropeCruises, HawaiiCruiseOutlet, RegentCruises, and CruiseCheap) specialists and advisors. Cruise ratings also may vary on the ship's age, size, cabins/venues/amenities, passenger feedback, etc. Besides CLIA and WMPH, other cruise vessel rating sources are Berlitz Guide, Fieldings Guide, Sterns Guide, CruiseCritic, CruiseReviews, and CruiseMates.

Cruise ship star ratings meaning

5,5 stars rating - a top luxury cruising, impeccable and highly personalized service, finest quality food & amenities; attention to detail, perfect maintenance, spacious accommodations, gourmet cuisine, the highest level of service, authentic furnishings, top of the line fitness & spa facilities.

5 stars rating - the highest level of food/service in a premium cruising market, high-quality meals, attentive service, well-equipped staterooms (not necessarily large), list of cabin amenities include bathrobes; butler service, public spaces are with beautiful decors.

4,5 stars rating - friendly decor, good maintenance, full range of onboard activities.

4 stars rating - best overall experience, above-average food & service, satisfactory entertainment.

3,5 stars rating - an average overall experience, very small to large accommodations, good service, delicious food, kids facilities without dedicated areas, mediocre entertainment.

3 stars rating - modest experience on an older cruise ship, may not have balcony cabins, mediocre food & lack of proper service, expect interesting destinations/itineraries.

2 stars rating - the ship is comparable to a low-budget hotel, a major refurbishment needed for refit and renovation of public areas and staterooms, lousy service (the staff will only supply the most basic service), itineraries with little or no popular (cheap charging) ports of call.

Full List: The 10 Current Largest Cruise Ships on the Planet

If you think cruise ships have gotten bigger, it’s not just your imagination. Whereas a ship built in the 1990s might hold 2,500 passengers and come in at around 75,000 gross tons (a measure of ship size), that’s nowhere near the ships built today.

Today, any new ship from a major line will be at least 140,000 gross tons, with many much larger than that. Passenger counts have also swelled, with many new ships carrying 5,000 cruisers when completely full.

But the largest cruise ships on the planet are in another league altogether. They can measure up to 250,000 gross tons (roughly triple the size of a ship built 30 years ago!) and when at full capacity with crew, have nearly 10,000 people onboard.

Why Are Cruise Ships So Big?

Truth be told, while the size of massive modern ships is staggering, not everyone likes the large ship experience. Some people can find them too crowded and too hard to navigate. But not everyone feels that way, and cruise lines have invested literally billions into building ships that are as large as possible. So what is the appeal of a mega ship?

Amenities/Activities: For passengers, the big advantage of size comes with everything that can be fit onto the ship. Instead of the old days where there was a pool, some loungers, and a buffet, modern mega ships are literal resorts at sea.

There are multiple pools, more than a dozen restaurants, casinos, ziplines, literal parks, ice-skating rinks, rock-climbing walls, spas, and more bars than you can count on your fingers and toes.

All of that combines into an experience that can exceed expectations and keep passengers coming back for more.

Efficiencies of Scale: For cruise lines, one big positive about a larger ship are greater efficiencies. Instead of having the cost of building two smaller ships — and the costs of having two sets of crew to run them both — one larger ship offers the chance for just as many passengers at a lower cost.

Marketing: Finally, one overlooked aspect of why cruise ships are bigger than ever has to do with marketing and publicity. There’s a certain awe and interest that comes with the world’s largest ships. Seeing them in port is essentially a giant billboard for a cruise line. And the largest ships also get significant press due to their size. All of that can translate into more interest, ticket sales, and prices for the newest — and biggest — ships.

With that in mind, here is the current list of the world’s largest cruise ships as of now…

Icon of the Seas

When it comes to the largest ships, Royal Caribbean is the undisputed leader with the six biggest cruise ships in the world. But the king of the fleet — and the largest cruise ship in the world — is Icon of the Seas .

Icon of the Seas doesn’t sail with passengers until 2024, but it’s already made waves. It’s not just the massive size (250,800 gross tons and 7,600 passengers at maximum capacity), but what’s onboard. A full-fledged waterpark, seven different pools, and eight different neighborhoods offer a spot for everyone. This ship looks to change cruising forever.

• Gross Tonnage: 250,800
• Length: 1,198 feet
• Passenger Capacity: 5,610 double occupancy; 7,600 max capacity
• Year Built: 2023

Wonder of the Seas

Wonder of the Seas is the latest edition of Royal Caribbean’s Oasis-class ships (until Utopia of the Seas arrives in 2024), which were the largest class in the world until the new Icon class took the torch. Still, it’s not as if Wonder of the Seas is a slouch.

At 235,600 gross tons, there’s room for 7,084 passengers and an amazing amount to see and do onboard. This includes Central Park, the mid-ship outdoor promenade that winds through lush gardens, and the AquaTheater, where performers put on aquatic shows, including towering high dives at sea.

• Gross Tonnage: 235,600
• Length: 1,188 feet
• Passenger Capacity: 5,734 double occupancy; 7,084 max capacity
• Year Built: 2022

Symphony of the Seas

Each iteration of Oasis-class ships has arrived just slightly larger than the previous when it comes to gross tonnage. That means they each had their time as the largest in the world before another arrived on the scene. In this case, Symphony of the Seas (228,000 gross tons and the ability to hold 6,680 passengers) took the crown in 2018.

Today, it’s the third-largest cruise ship on the planet, but it’s no slouch. It holds seven different neighborhoods, nearly 3,000 staterooms, three waterslides, and Ultimate Abyss — a 10-story dry slide.

• Gross Tonnage: 228,081
• Passenger Capacity: 5,518 double occupancy; 6,680 max capacity
• Year Built: 2018

Harmony of the Seas

Built in 2016, Harmony of the Seas features 18 decks, more than 225,000 gross tons (about 10% smaller than Icon of the Seas) and can carry nearly 6,700 passengers when completely full. That’s good enough to make it the fourth-largest cruise ship in the world.

It features many of the same components of other ships in the class, like the adults-only Solarium, Central Park, and the AquaTheater. That’s not to mention 17 different spots to grab a bite to eat.

• Gross Tonnage: 226,963
• Passenger Capacity: 5,479 double occupancy; 6,687 max capacity
• Year Built: 2016

Oasis of the Seas

The ship that started the trend of truly mega ships is also the namesake of the Oasis class — Oasis of the Seas. If you notice, most of the largest ships on our list were built recently. This ship first began sailing in 2009 and set off the “arms race” of larger ships that continues today.

Following a refurbishment, it now features three waterslides, a dozen lounges, 2,801 cabins (including one with a panoramic view right above the ship’s bridge), a splash pad for kids, and even an escape room themed like the 1960s NASA mission control. And did we mention 20 different places to find something to eat?

• Gross Tonnage: 226,838
• Length: 1,187 feet
• Passenger Capacity: 5,602 double occupancy; 6,771 max capacity
• Year Built: 2009

Allure of the Seas

Following a refurbishment of Oasis of the Seas, Allure of the Seas — which was the second ship in the class and built in 2010 — is actually now the smallest of the group based on tonnage. Still, that’s good enough for sixth largest in the world at “just” 225,000 gross tons.

On the ship, you’ll find 18 decks, 2,748 staterooms and more than 6,800 passengers when completely full. That’s definitely a lot of people, but remember that you also have a lot more space to spread out, giving plenty of elbow room.

• Gross Tonnage: 225,282
• Passenger Capacity: 5,496 double occupancy; 6,826 max capacity
• Year Built: 2010

MSC World Europa

While Royal Caribbean has a lock on the largest ships, the title of largest cruise ship from outside that cruise line goes to MSC World Europa.

Coming in at almost 216,000 gross tons, it’s roughly 14% smaller than Icon of the Seas. But don’t think it’s some slouch. From bumper cars to seven pools to an 11-story slide, there’s no shortage of things for kids to do. Adults will love the 13 different dining options and an indoor promenade or Panorama Lounge for shopping, having a drink, or just relaxing.

This ship will be joined in 2025 by sister-ship MSC World America, set to sail stateside.

• Gross Tonnage: 215,863
• Length: 1,094 feet
• Passenger Capacity: 5,231 double occupancy; 6,762 max capacity

Costa Smeralda/Costa Toscana (Tie)

These two ships come in at a tie for the eighth-largest cruise ship in the world. Built in 2019 and 2021, respectively, they both belong to Costa Cruises. And if the shape of the ship looks familiar, that’s because Costa is a sister line to Carnival. A similar design is used for Carnival’s largest ships, Mardi Gras, Celebration, and Jubilee. However, those ships come in just under the 185,000 gross tons seen with Smeralda and Toscana.

Both ships offer 13 pools and hot tubs, nearly a dozen restaurants and just under 20 bars and lounges. And if you like balcony views? There are 1,550 balcony rooms on each, providing plenty of options for the roughly 6,500 passengers that can sail at full capacity.

• Gross Tonnage: 185,010
• Length: 1,106 feet
• Passenger Capacity: 5,224 double occupancy; 6,554 max capacity
• Year Built: 2019/2021

P&O Arvia

Taking the crown as the 10th-largest cruise ship in the world is Arvia from P&O Cruises. Measuring just under 185,000 gross tons, it offer a similar design to ships like Costa Smeralda and Carnival Celebration, but don’t think these ships are all the same.

For instance, Arvia features a unique Skydome area that is a pool area with retractable roof by day and an entertainment venue by night. It also features its own rum distillery onboard, meaning you can take home rum literally made on the ship. Kids will love the Altitude zone that features a ropes course, mini-golf, and more. There’s also Mission Control, a submarine-themed escape room.

All told, a reported 6,685 passengers can enjoy the ship at one time.

• Gross Tonnage: 184,700
• Length: 1,130 feet
• Passenger Capacity: 5,200 double occupancy; 6,685 max capacity

The top 10 biggest cruise ships in the world

M odern cruise ships continue to grow in size, with the biggest cruise ship, the Icon of the Seas , launching at the start of this year, and her sister ship the Star of the Seas expected to surpass her in size.

Both of these ships are operated by Royal Caribbean International, which operates five of the ten largest cruise ships in the world. Carnival Corporation, arguably the biggest cruise company in the world, features three times on the list through its subsidiaries P&O Cruises and Costa Cruises.

All of the heaviest cruise ships in the world were built within the last 20 years, although the majority – six of the ten – were built within the last five years.

So, here are the top ten biggest cruise ships in the world, by gross tonnage. 

10. P&O Cruises MS Arvia : 185,581 gross tonnes

The MS Arvia is P&O Cruises’ fourth ship to be built by German shipyard Meyer Werft. Weighing in at 185,581 gross tonnes, the 345m (1,130-foot) Arvia is slightly larger than her sister ship, the MS Iona . The 20-deck ship is the largest ship commissioned for the British cruise market and has a maximum passenger capacity of 6,264 passengers, with 1,800 crew onboard. 

The ship is the second liquefied natural gas (LNG)-powered Excellence-class vessel for P&O, following the Iona . Arvia is powered by a 61,760kW LNG drive system, with a propulsion power of 37 megawatts. The LNG-powered propulsion system allows the vessel to sail at a maximum speed of 21.5 knots.

After being floated out in August 2022, the Arvia mainly operates itineraries around the Caribbean or the Mediterranean.

9. Costa Cruises – Costa Smeralda : 185,010 gross tonnes

The Costa Smeralda is the first LNG-powered vessel in the Costa Cruises fleet. With a gross tonnage of 185,010gt, the 20-deck Excellence-class ship measures 337m (1,106 feet) in length. The second LNG-powered cruise ship to enter operation in the world, she has a maximum capacity of 6,554 passengers with 1,646 crew and a service speed of 21.5 knots.

Construction of the Costa Smeralda began at the Meyer shipyard in Turku, Finland, in September 2017. Meyer Turku collaborated with the Meyer Werft Papenburg shipyard to develop and integrate the LNG propulsion plant for the ship. She is fitted with four 16-cylinder, Caterpillar MaK 16VM46DF engines, with 15.4 megawatts (20,710 horsepower) output per engine, resulting in a maximum power of  37 megawatts (50,000 horsepower).

The ship, which was named after the Emerald Coast of Sardinia, entered service in December 2019 , departing Savona on its maiden voyage in the Mediterranean, where it has sailed since.

8. Costa Cruises – Costa Toscana : 186,364 gross tonnes

The Costa Toscana is the sister ship of the Costa Smeralda and is also powered by LNG . measuring 337m (1,106 feet) long and weighing in at 186,364 gross tonnes, the Toscana has a maximum capacity of 6,338 passengers and 1,678 staff across her 20 decks.

Like her sister ship, the Toscana was also built at the Meyer shipyard in Finland, with construction completed in 2021. She is also powered by four MaK-Caterpillar engines, with a total power of 57.2 megawatts (76,706 horsepower), and two ABB Azipod motors , resulting in a service speed of 17 knots.

Named in homage to the Tuscany region of Italy, Costa Toscana mainly sails around the Mediterranean Sea but Costa Cruises has also used the ship to sail itineraries further afield, such as around Brazil and the UAE.

7. MSC Cruises – MSC World Europa : 215,863 gross tonnes

The only entry in the top ten from MSC Cruises, MSC World Europa measures 333m (1,094 feet) in length. With 215,863 gross tonnage, she can house more people than any other ship in the MSC fleet: up to 6,762 passengers across 2,633 cabins spread over 22 decks, in addition to 2,138 crew.

Built by Chantiers de l’Atlantique in Saint-Nazaire, France, the World Europa ’s LNG-power propulsion system was subcontracted to Finland-based Wärtsilä. Five LNG-powered, 14-cylinder Wartsila 46DF dual-fuel engines power the vessel, with a propulsion power of 44 megawatts ( 59,005 horsepower). She also features nitrogen oxide reduction (NOR) units, two Wartsila LNGPac fuel storage and supply systems, seven thrusters, and two fixed-pitch propellers. 

The MSC World Europa was floated out at the end of 2021 and was initially used as an accommodation vessel for fans attending the 2022 FIFA World Cup, with the ship berthed at Doha Port in Qatar during the tournament. Following the competition, the ship subsequently travelled several routes around the UAE, before sailing to the Mediterranean, where it has sailed itineraries since.

6. Royal Caribbean International – Allure of the Seas : 225,282 gross tonnes

The first of many entries on this list operated by Royal Caribbean, Allure of the Seas weighs in at 225,282 gross tonnes. Measuring 362m (1,187 feet), she is only 50mm (2 inches) longer than her sister ship the Oasis of the Seas . The Allure has a maximum capacity of 6,780 passengers and 2,200 crew across 18 decks.

Built at the Turku Shipyard in Finland, the Allure took two years to build , floating out in 2010. She features six Wärtsilä 46 diesel engines with a total power output of 97 megawatts (130,053 horsepower). It is propelled by three electric Azipod azimuth thrusters. The ship can travel at a cruising speed of 22 knots.

With a homeport of Galveston, Texas in the US, the Allure mainly serves itineraries around the Bahamas but she is scheduled to sail routes around the Mediterranean in 2025.

5. Royal Caribbean International – Oasis of the Seas : 226,838 gross tonnes

The oldest ship on this list, the Oasis of the Seas has been in service for over a decade. She was the biggest cruise ship at the time when floated out in 2009, with a gross tonnage of 226,838gt and a length of 360m (1,181 feet). The Oasis has a maximum capacity of 6,699 passengers and 2,181 staff across 18 decks.

The Oasis took two years to build at the Meyer shipyard in Turku, Finland, with the keel laid on 12 November 2007 and the ship arriving at her homeport of Port Everglades in Florida, US, on 13 November 2009.

The Oasis is powered by eight Wärtsilä V12 diesel engines, which generate 5.6 megawatts (7,500 horsepower) each, alongside four bow thrusters. The main propulsion system consists of three 20-megawatt (26,820 horsepower) electric Azipod motors, resulting in a combined propulsion power of 82 megawatts (109,964 horsepower) and a standard cruising speed of 23 knots.

The Oasis mainly operates routes around the Caribbean, but occasionally repositions to offer itineraries in the Mediterranean.

4. Royal Caribbean International – Harmony of the Seas : 226,963 gross tonnes

The third Oasis-class ship built by Royal Caribbean, Harmony of the Seas weighed in bigger than her existing sister ships at launch in 2016, with 226,963 gross tonnage, but she has since been surpassed by newer vessels. With a total length of 362m (1,188 feet), Harmony has a maximum capacity of 6,780 passengers and 2,300 staff across 18 decks.

Royal Caribbean placed an order with STX France for the construction of Harmony of the Seas in December 2012. The first steel for the ship was cut at STX France’s Saint-Nazaire shipyard in September 2013, while the keel-laying ceremony was held in May 2014.

The Harmony is powered by three 18.9-megawatt Wärtsilä 16V46 16-cylinder main generator diesel engines and three Wärtsilä 12V46 12-cylinder engines producing 13.9 megawatts each. The propulsion power is provided by three electric Azipod azimuth thrusters and manoeuvring is assisted by four 5.5-megawatt Wärtsilä CT 3500 tunnel thrusters. The propulsion system results in 82 megawatts (109,964 horsepower) and enables the ship to sail at a standard speed of 23 knots.

Harmony of the Seas embarked on her inaugural seven-night Western Mediterranean cruise from Barcelona, Spain, in June 2016, and currently operates itineraries around the Western Caribbean from her homeport of Galveston, Texas in the US.

3. Royal Caribbean International – Symphony of the Seas : 228,081 gross tonnes

At launch in 2018, the Symphony of the Seas surpassed the Harmony as the biggest cruise ship, weighing in at 228,081 gross tonnes. Measuring 361m (1,185 feet), the Symphony has a maximum capacity of 6,680 passengers and 2,200 staff across 18 decks and was the testing ground for Royal Caribbean's new muster drill . With a total length of 361m (1,185 feet), She is roughly 30 metres (98 feet) longer than the largest military ships , the US Nimitz-class aircraft carriers and the USS Gerald R. Ford .

The keel-laying ceremony for the Symphony of the Seas was held in October 2015 at STX’s Saint-Nazaire shipyard in France, and the ship sailed out in June 2017. She is powered by six diesel sets, each composed of three Wärtsilä 16V46D engines and three Wärtsilä 12V46D engines, as well as three 20-megawatt electric Azipod main engines – resulting in 82 megawatts (109,964 horsepower) of propulsion power and a standard cruising speed of 22 knots.

The Symphony commenced her seven-day maiden voyage from Barcelona in April 2018, and since then has mainly operated itineraries around the Caribbean from her homeports of Miami, New York, and Fort Lauderdale.

2. Royal Caribbean International – Wonder of the Seas : 235,600 gross tonnes

Royal Caribbean's flagship, Wonder of the Seas is the fifth Oasis-class cruise ship built for the cruise company. Weighing in at 235,600 gross tonnes, the Wonder was the largest ship in the world when she was completed in January 2022. Measuring 362m (1,187 feet) in length, the 18-deck Wonder has a maximum capacity of 7,084 guests across its 2,867 staterooms, as well as housing 2,369 crew.

Built by Chantiers de l’Atlantique in Saint-Nazaire, Wonder is powered by two Wärtsilä 16V46D engines and four Wärtsilä 12V46D engines; and uses three 20-megawatt electric Azipod engines for propulsion, combining for a propulsion power of 82 megawatts (109,964 horsepower and a standard cruising speed of 22 knots.

The Wonder sailed her maiden voyage in March 2022 from Fort Lauderdale, Florida, and has since served itineraries around the Caribbean from her homeports of Miami and Cape Canaveral.

1. Royal Caribbean International – Icon of the Seas : 248,663 gross tonnes

Weighing 248,663 gross tonnes and measuring 365 metres (1,1967 feet), the Icon of the Seas is the largest cruise ship in the world. Christened on 23 January 2024, the Icon has a maximum capacity of 7,600 passengers and 2,350 crew across 20 decks. She is the lead ship of the new Icon-class, with a sister ship the Star of the Seas due to be delivered in 2025 and another ship planned for delivery in 2026.

Built by Meyer Turku in Finland, the Icon is the first ship in the Royal Caribbean fleet that can be powered by LNG. It uses three Wärtsilä 14V46DF and three Wärtsilä 12V46DF for its main generator engines, which provide 67.5 megawatts of energy to run the ship. She is propelled by three 20-megawatt Azipod thrusters as well as five 4.8-megawatt Wärtsilä WTT-45 CP bow thrusters, with a cruising speed of 22 knots.

After sailing her maiden voyage on 27 January 2024, the Icon now sails year-round itineraries of seven-night trips around the Eastern and Western Caribbean from her homeport of Miami, Florida.

Things To Do

Travel | a look inside the world’s largest cruise ship, the icon of the seas.

Right under it is a majestic staircase, one reminiscent of an Italian palace, that takes guests up to the Pearl Café on one side and a Latin nightclub on the other. Tall windows abound.

The Pearl structure allows the ship to have a much more open design and layout, which results in far greater natural light and exposure to the sea when compared to other vessels owned by Royal Caribbean International.

“One reason the Pearl exists is to get ocean views at the heart of the ship,” said Jay Schneider, Chief Product Innovation Officer for Royal Caribbean, in an interview with the Miami Herald. “It feeds the energy of the royal promenade.”

After much anticipation and hype, the 1,198-feet-long vessel with a capacity of 5,610 guests reached PortMiami on Jan. 10. It will be based there year-round, focused on weeklong or shorter trips to the Caribbean. Royal Caribbean International’s headquarters are also located there.

It has over 40 restaurants and drinking establishments including two dueling piano bars, three-story townhouses for large families, and over 33,000 plants in what it dubs Central Park, one of its neighborhoods.

About 1,000 people visited the Icon and its 19 decks on Jan. 11. They were largely media and employees with Royal Caribbean.

Employees then began a two-night demo cruise Thursday night to the Bahamas. Royal Caribbean will have a few more short trips for them, their families, and then travel agents and VIPs. That all comes ahead of its first cruise for the public, scheduled for Jan. 27.

Inside the world’s largest cruise ship

The Icon of the Seas is the first new class of ships from Royal Caribbean in nearly a decade. With 2,850 staterooms; 18 guest decks; 7 pools, each with two lifeguards; and 2,350 crew, it is considered by cruise industry experts the largest cruise ship in the world at the moment.

Schneider, Royal Caribbean’s chief product innovation officer, told the Herald there were multiple goals in creating this new class of ship. One was making it easier to get around.

“We’ve heard over the years challenges guests have had with movement around the ship,” said Schneider. “Our focus has been to dramatically improve that.”

The Pearl is one of their solutions. The open structure permits passengers to go from Deck 2 to Deck 8 without having to go out of the way to find an elevator.

The company also sought to open up its venues. For example, it has the Latin nightclub on its other ships but with a closed facade. On the Icon, they removed the facade.

Another main objective with the Icon is to provide what the Royal Caribbean executive called “unrivaled water experiences,” or to surround passengers by water or the ocean as much as possible. That means pools facing the sea — one is at one edge of the ship — and even beds that can be adjusted to ensure they face the ocean.

“You are going to have this whole sense that you are part of this ship but also part of the sea,” said John Lovell, president of Travel Leaders Group.

On Chill Island on Deck 16 is a swim-up full-service bar called Swim & Tonic. Guests can order and imbibe drinks while seated in chairs half-immersed in the pool or hot tub. And whichever option one chooses, there’s a great view of the sea.

Thrill Island, also on Deck 16 and one of eight neighborhoods, has six waterslides, a surfing area, a rock-climbing wall facing the ocean, and a mini-golf course. An adventure called Crown’s Edge allows thrill seekers to hang 154 feet above the ocean.

Royal Caribbean also wanted to up its game in catering to families and in providing food and entertainment, Schneider said.

At the highest end is the Empire Supper Club, which offers eight-course meals, including caviar and wagyu. Every dish there is paired with a drink.

Most eateries though are casual such as a family-style Italian restaurant and Pearl Café which makes fresh sandwiches, ready-made salads, and deserts. Izumu offers Japanese street food and Japanese taiyaki ice cream and there are more Hibachi tables on the Icon.

Sorrento’s, a popular pizza slice place on Royal Caribbean’s Oasis class of ships, is redesigned with more counter space and with the goal of reducing lines and improving flow of guests, which was becoming a complaint.

“We wanted to get rid of the lines as much as possible,” Schneider said.

Pearl’s Café’s importance stems from feedback the company got that passengers want more food that they can take out or grab and go when in a rush, especially those with kids who are on the move.

The final details

Little about the Icon has been rushed. It’s been a long time in the making, going back to at least 2017.

The general plan for the ship and arrangement of decks were all locked in by 2018. The design of the interiors and the number of rooms were finalized by 2019. Construction broke ground with steel cutting in June 2021.

Still, in recent weeks and months, work has not stopped. After construction at the Meyer Turku shipyard in Turku, Finland, there were sea trials last June, October and November.

A Herald reporter visited Schneider at his office in Miami on Nov. 13, days after he returned from Finland and right after the final sea trial.

He said then that they had a list of about three dozen requested changes to try to make.

In one case, his team noticed that planned lights fixed on the counter of the lobby bar were in reality much bigger than they seemed on paper, reducing guests’ access to the bartenders.

And so, those lights “are all getting removed,” said Schneider.

Meanwhile the company decided then it should up its game in mini-golf and make the course more tied to Thrill Island and thematic. So, in November, it added sunken boats and a fallen plane.

Thrill Island itself only came together the past two years.

In 2021, the ship had four waterslides and one tower, and then six but still one tower. It also had a rock-climbing wall farther away. But that did not seem right, so they decided to bring them all closer together.

They also added a second tower. The goal is now that at full capacity, if every kid wants to go on a ride, wait times will be under 20 minutes, Schneider said.

Meanwhile, at the Pearl Café, as of November, it had a glass barrier between the coffee barista at one end and customer. The original idea was that the guest would order coffee and then receive it at the other end of the counter on the assumption he or she bought other items like sandwiches or pastries. And there would be one point of sale.

But on one of the many walk-throughs the company did, the food and beverage team objected to the glass barrier between the coffee barista and customer, thinking it impeded flow of guests.

“It looked great designed this way but as we started to operationalize, the team said it’d be really helpful if we didn’t have the glass panel over there,” said Schneider.

On Jan. 11 there was no glass barrier.

Princess Cruises ships ranked by size from biggest to smallest — the complete list

Are you looking for the most venue-packed, resort-like Princess Cruises ships at sea? If so, you'll want to get on one of the biggest Princess cruise ships.

The biggest Princess cruise ships are, by their very nature, the Princess ships with the most onboard restaurants, bars and showrooms, as well as the most sprawling decktop pool and lounge areas. The biggest Princess ships have the biggest casinos and spas among ships in the Princess fleet and the most cabins and suites — and the most variation in cabin and suite types.

With room for 4,000 passengers or more, the biggest Princess ships are truly large resorts of the sort you find at the biggest vacation destination on land. If you're in the "bigger is better" camp when it comes to a resort experience, these are the Princess ships for you.

Still, Princess doesn't just operate large vessels. The Los Angeles-based cruise giant — the fifth largest cruise line in the world — also has several relatively small cruise ships in its fleet that carry just 2,000 or 3,000 people and have a more intimate feel. In some cases, these vessels are nearly 40% smaller than the size of Princess Cruises' biggest ships. These smaller ships, notably, have less deck-top pool space and fewer interior venues than the biggest Princess cruise ships. However, with fewer people on board, that's not necessarily a bad thing.

The smallest Princess cruise ships are best for vacationers who like a more intimate, less crowded resort experience.

What is the biggest Princess cruise ship?

The biggest Princess cruise ship is the 3,660-passenger Discovery Princess, which is also the line's newest vessel. It debuted in March 2022.

Discovery Princess is the sixth and final vessel in the Royal class of Princess ships that began rolling out in 2013. They all are roughly the same size, but Discovery Princess is just a tad bigger than its sister ships at 145,000 gross tons. The other five ships in the Royal-class series measure from 142,229 to 144,650 gross tons. Note that gross tons is a size measurement referring to interior space, not weight.

The ships in Princess' Royal class are significantly bigger than the ships in the line's other two classes of vessels (the Grand class and Coral class) and have more restaurants, bars, showrooms and deck-top pool space than the nine vessels in those classes.

The other Royal-class vessels that are similar in size to Discovery Princess are Enchanted Princess, Sky Princess, Majestic Princess, Regal Princess and Royal Princess.

For more details on Discovery Princess, including what venues are on board and what it's like to sail on the vessel, see TPG's first impressions of Discovery Princess after an early sailing.

What is the smallest Princess cruise ship?

The smallest Princess cruise ship is the 2,000-passenger Coral Princess. Measuring just 91,267 gross tons, it's about 36% smaller than Discovery Princess, making it a significantly smaller vessel.

Coral Princess dates to 2002, a time when cruise ships were built far smaller than they are today and with far fewer venues. At 21 years old, it's also one of the two oldest vessels in the Princess fleet and will probably be phased out sometime in the next decade.

While significantly smaller than the newest Princess ships, Coral Princess still has many of the signature spaces and venues found on new Princess vessels, including an Italian eatery called Sabatini's and a steakhouse.

Entertainment venues on Coral Princess include a relatively large main theater for production shows, a secondary lounge that offers comedy shows and other entertainment, and a casino. Like other Princess ships, the top deck of the vessel is mostly devoted to pool areas with hot tubs and lounge chairs. There's also a spa.

While smaller and older than the typical Princess ship, Coral Princess has a loyal following among Princess fans who prefer smaller and more intimate ships.

Are bigger Princess cruise ships coming?

Yes! Princess currently has two new, bigger cruise ships on order. The first to arrive will be Sun Princess in February 2024. This will be the first of an all-new Sphere class of vessels for the line that will be made up of ships that will be notably bigger than anything Princess has had in its fleet before.

Measuring 175,500 gross tons, Sun Princess will be about 21% bigger than the biggest Princess cruise ship currently at sea — a significant increase. It'll be nearly double the size of the smallest Princess ships currently at sea.

The second new ship that Princess has on order, to be called Star Princess, will be a sister vessel to Sun Princess of a similar size. It's due to begin sailing in 2025.

The Sphere-class vessels are currently under construction at the Fincantieri shipyard near Monfalcone, Italy.

Note that this isn't the first time Princess has named a ship Sun Princess or Star Princess. Both are recycled names from past Princess ships. Princess operated smaller vessels under the Sun Princess and Star Princess names up until 2020.

TPG recently got a sneak peek at the most notable new features under development for the new Sun Princess during a visit to the partly completed vessel at the Fincantieri shipyard.

In addition to being significantly bigger than past Princess ships, the new Sun Princess will also be the first Princess ship with suites that come with exclusive access to a private restaurant, lounge and sun deck — a sign Princess is hoping to draw more upmarket travelers.

In all, the vessel is designed to hold 4,300 passengers at double occupancy.

What's the difference between bigger and smaller Princess ships?

The biggest Princess cruise ships have room for more onboard venues and attractions than smaller Princess ships. That makes them more alluring for vacationers who prefer a big resort experience with lots of options as compared to a stay at a smaller resort.

On the biggest Princess vessels, the Royal-class vessels, for instance, you'll find the largest piazza-like central atriums in the Princess fleet surrounded by lots of bars and restaurants; multiple entertainment venues for live shows, comedy acts and more; and expansive pool decks with more space for sunning than you'll find on smaller Princess vessels.

You'll also find some only-on-the-Royal-class-ships extras, including, on some of the ships, a glass-floored "SeaWalk" that extends over the side of the vessel.

Princess' smaller cruise ships also generally are its older cruise ships and lack some of the above features, which are more typical of newer ships. These smaller Princess ships have a more intimate feel, at least in the pantheon of relatively big, mass-market ships, and they hold fewer people.

While Royal-class ships can hold more than 4,500 passengers with every berth full, the line's smaller vessels (particularly the relatively small Island Princess and Coral Princess) often sail with just 2,000 or so passengers on board.

That makes the smaller Princess ships a good choice for someone who wants to try Princess but isn't eager to travel with huge crowds. The smallest ships in the Princess fleet thus appeal to a subset of Princess fans who prefer more intimacy in a cruise vessel and don't mind giving up some onboard amenities to get it. They are also often less expensive to sail on, on a per-day basis.

In addition, because of their size, the smallest ships at Princess Cruises are able to operate itineraries to places that aren't as easy for big ships to visit. Not all ports in the world can handle a ship the size of Discovery Princess.

Icon of the Seas

Scheduled to set sail in early 2024, the Icon of the Seas is one of the most celebrated and anticipated new cruise ships across all the major cruise lines. This Icon Class vessel was built to dazzle and entertain cruise passengers of all ages, and it features eight unique neighborhoods, seven pools and the largest waterpark at sea.

In total, Icon of the Seas offers 2,805 individual staterooms with space for 7,600 guests at maximum and 2,350 crew members. The vessel is 1,198 feet long with gross tonnage of 250,800.

Utopia of the Seas

Royal Caribbean's Utopia of the Seas is another vessel that is set to debut in 2024 with sailings from Port Canaveral, Florida. This Oasis Class ship will offer up a total of 2,834 guest rooms and is 1,188 feet in length and 236,860 gross tons in size.

Odyssey of the Seas
