While their older ships may not come outfitted with everything that is onboard the newer ships, you are sure to find a ship and itinerary that meets you and your travel party's wants and needs!
Below, we have broken down Royal Caribbean's fleet by ship size and by ship class!
Icon Class
Icon of the Seas (Expected in 2024)

The first ship in Royal Caribbean's Icon Class, Icon of the Seas, has not officially entered service. She will launch in January 2024, with the current projected maiden voyage scheduled to depart on January 27, 2024 from Miami, Florida.
Fans of Oasis Class ships will notice that the Icon Class takes inspiration from this class with the different neighborhoods and inward facing balcony cabins; however, guests can expect numerous Royal Caribbean firsts, including Thrill Island, the largest waterpark at sea that will feature 6 record breaking water slides; an infinity-edge pool; new family-oriented Surfside neighborhood; and AquaDome.
Icon of the Seas will be joined by two more unnamed Icon Class ships in 2025 and 2026, respectively.

Oasis Class
Royal Caribbean's Oasis Class currently the has the biggest cruise ships at sea and offers passengers seemingly endless options for activities, dining, and entertainment.
It was the first class of ships in the world to feature the concept of neighborhoods that offer distinct experiences based on personal styles, preferences, or moods. If, for instance, you're looking for a serene escape from the crowds, you might find yourself wandering through Central Park admiring the thousands of live plants. They were also the first to feature interior facing balconies in said neighborhoods.
There are currently 5 Oasis Class ships. The 6th, Utopia of the Seas, is expected to enter service in 2024; however, the cruise line has yet to confirm any details regarding the ship's inaugural season.
Wonder of the Seas (2022)

Wonder of the Seas currently the largest cruise ship in the world and the fifth Oasis Class ship. Compared to other Oasis Class ships, she has some key differences that make her stand out in a bold way, such as a brand-new Suite neighborhood, upgraded Caribbean pool deck, and redesigned mini-golf course and Windjammer Buffet, which also happens to be the largest buffet in the fleet.
Through at least April 2025, she will be making round trip sailings to the Caribbean and Perfect Day at CocoCay from Port Canaveral, Florida.

Gross tonnage: 225,282
Length: 1,187 feet
Width: 215 feet
Number of passengers (double occupancy): 5,484

They are the only ships in the cruise line's fleet to feature attractions such as the North Star observation capsule, iFly skydiving simulator, SeaPlex multipurpose venue, and Two 70° lounge.
Spectrum of the Seas and Odyssey of the Seas are part of the Quantum Ultra Class, which combines the fan-favorites onboard standard Quantum Class vessels with upgraded amenities:

When Freedom of the Seas launched, she wad the first to feature a FlowRider surf simulator, the H2O Zone for kids, and cantilevered hot tubs. To date, it is Royal Caribbean's smallest class of ships at sea, comprised of only 3 vessels, all of which have received some sort of amplification.
Freedom of the Seas, for instance, has a Playmakers Sports Bar & Arcade, while Liberty of Seas features the only boomerang style slide in the fleet.
For that reason, there are some differences amongst the ships, so it is important to check and see if the one you are looking to sail on has the amenities you are hoping for, whether that is Independence's "Fish & Ships" or SkyPad virtual reality bungee trampoline or Freedom's resort-style pool deck.

Voyager Class
Royal Caribbean's renowned Royal Promenade first debuted on Voyager Class ships. They were also the first ships to feature an ice rink at sea!
Within this class, there are two generations of ships; the latter two vessels -- Navigator and Mariner of the Seas -- feature cabins with wider glass balconies.
In a way, these ships can be thought of as shorter versions of Freedom Class ships. And like Freedom Class ships, the onboard amenities can vary from ship to ship, as only three -- Voyager, Navigator, and Mariner of the Seas -- have undergone the Royal Amplification program.
Navigator of the Seas, for instance, is the only ship in the fleet to feature "The Blaster" water slide. Currently, it is the longest water slide at sea! While on Mariner of the Seas, guests will find a SkyPad, a virtual reality bungee trampoline.

Radiance Class destinations include Alaska, Australia & New Zealand, the Bahamas, Canada & New England, Caribbean, Europe, Hawaii, Pacific Northwest, Panama Canal, and the South Pacific.
They are the perfect class of ship for those seeking a more traditional cruising experience that highlights intimacy and port-intensive itineraries.

All of these ships offer a relaxing, no-frills cruising experience with few onboard "thrills" that the define the newer ships. That being said, you will still find an adults-only Solarium with retractable roof, rock wall, mini-golf, and a pool deck.
These smaller ships are fan-favorites due to their limited occupancy, and guests enjoy the more intimate and personalized service that they are able to receive.
Today, you will find all four Vision Class ships sailing across to the world to destinations like Bermuda, Canada & New England, the Caribbean, and Europe.
Enchantment of the Seas (1997)

Enchantment of the Seas is the biggest ship in the Vision Class and offers some different features than her sister ships. In 2005, the ship was actually cut apart in the middle and extended by 73 feet. It is also the only ship in the class to feature a Jump Zone, a set of four bungee trampolines.
