Its global footprint is supported by strategic partnerships with local ports and tour operators, enabling seamless shore excursions and immersive cultural experiences.

Flagship Vessels and Onboard Innovation

Royal Caribbean is known for pushing the boundaries of cruise ship design. Its Oasis-class ships are the largest passenger vessels in the world by gross tonnage and passenger capacity. The latest addition, Icon of the Seas, launched in early 2024, is the largest cruise ship ever built, measuring 250,800 gross tons and accommodating up to 7,600 passengers.
