Royal Caribbean International: The Ultimate Guide to the World’s Boldest Cruise Line
When it comes to mega-resorts at sea, Royal Caribbean ships are some of the largest and most innovative cruise ships in the world, spanning Oasis, Icon, Freedom, Voyager, Radiance, and Quantum class vessels within Royal Caribbean International's fleet. Part of Royal Caribbean Group alongside Celebrity Cruises, RCI operates one of the industry's biggest fleets, and this page serves as a complete list of Royal Caribbean ships. You'll find the key differences between classes, how ship size is measured by gross tonnage and passenger capacity, and what each vessel offers in dining, entertainment, amenities, and the latest additions to the fleet.

Royal Caribbean delivers a high-energy, multi-generational vacation experience that blends thrills, world-class dining, and Broadway-caliber entertainment, so knowing how the fleet has evolved over nearly three decades makes it much easier to choose the best ship for your style of cruise.
