Today, the largest cruise ships in the world feature not only the latest and greatest in technology and luxurious amenities, but they offer some activities and entertainment never before seen in a cruise-ship setting. Here is a look at the five largest cruise ships in the world, based on ship’s length, all of which happen to belong to the Royal Caribbean fleet.

Symphony of the Seas debuted in 2018 and took over the number one spot from its sister ship, Harmony of the Seas. This 228,081-ton mega-ship is 1,188 feet long and over 215 feet wide. It can hold up to 6,680 passengers with 2,759 cabins. The ship is so big, it’s even divided into seven “neighborhoods.”

Passengers on Symphony of the Seas will have access to 24 pools, surf simulators, whirlpools and waterslides, including the Ultimate Abyss, which features a 92-foot drop to the decks below. There are hot tubs for some adult relaxation and Splashaway Bay water park for the younger guests.

For the more adventurous cruisers, check out the zipline on the ninth deck or one of the two 43-foot rock climbing walls. Passengers will have no shortage of dining options after a busy day thanks to the ship's 22 restaurants, including an Alice in Wonderland-inspired spot and a bar that has robot bartenders serving up your favorite cocktails.

Harmony of the Seas entered service in 2016 and holds the record for the second largest ship in the world at 1,118 feet long and 226,963 tons. It can hold up to 5,479 passengers at double occupancy. Royal Caribbean’s Oasis-class ships have many of the same amenities and activity options.

Harmony of the Seas also features the signature Ultimate Abyss water slide like Symphony of the Seas with its 10-deck drop from the Sports Zone and pool on Deck 16 all the way down to Deck 6. The seven “neighborhoods” you’ll find on these mega-ships are divided into options like the Pool and Sports Zone, tree-lined Central Park and The Boardwalk, which even has a carousel.

With the debut of Symphony of the Seas, Allure of the Seas drops to the third spot for largest cruise ships in the world. This ship launched in 2010 and can accommodate up to 5,400 passengers at double occupancy. While it might be slightly smaller than its bigger sister Oasis-class ships, there is no shortage of things to do on Allure of the Seas. It has over 20 restaurants, surfing simulators and even an ice rink.

If you want to go at a more leisurely pace, wander down the Royal Promenade, where you will find bars, restaurants and pubs. Enjoy dinner and take in a Broadway musical in the Entertainment Place neighborhood. While there are a lot of activities and entertainment geared toward adults, Royal Caribbean includes a dedicated Youth Zone space for kids and teens on its Oasis-class ships as well.

Sparks joy? You better believe it.

When Oasis of the Seas arrived on the scene in 2009, it was really the first of its kind and raised the standard for cruising. It was the first of the Oasis-class of ships and introduced the first Tiffany & Co. boutique on a ship.

Another unique feature on the Oasis ships is the AquaTheater, which is the deepest pool at sea. Guests can take scuba diving lessons here, and it even has two 30-foot-high dive platforms. When the sun goes down, look for top-notch entertainment like aerial artists, synchronized swimmers and water jets that light up in sync to the music. If you really want to maximize the views here, book a two-bedroom AquaTheater Suite class of cabin that has wraparound balconies overlooking the theater.

Anthem of the Seas debuted in 2015 and at the time, it was one of the most expensive cruise ships ever built. Royal Caribbean Quantum-class ships feature some of the best technology you can find on a cruise ship. There is super-fast internet, a skydiving simulator, robotic bartenders and more. Anthem of the Seas even has nearly 400 cabins that have virtual balconies, which feature a full high-definition 80-inch screen connected to a live camera with audio so you can experience the same effect as someone with an ocean view or balcony cabin.

Head up to NorthStar where you can float high above the sea when the jewel-shaped capsule is raised 300 feet in the air. You can drive bumper cars, try rock climbing, get on the surf simulator, go roller skating or even sign up for trapeze school. At 1,142 feet long, Anthem of the Seas can hold 4,180 passengers at double occupancy.
