Wonder of the Seas is a Royal Caribbean Oasis-class cruise ship built by Chantiers de l'Atlantique at Saint-Nazaire and delivered in 2022. At delivery she was the world's largest cruise ship by gross tonnage (236,857 GT) and passenger capacity (5,734 lower berth, 9,288 maximum). She combines Royal Caribbean's signature Oasis-class features — multiple themed neighbourhoods, Central Park-style open-air promenade, AquaTheater amphitheatre — with a 7-deck Suite Class for premium passengers.
Oasis-class crews number roughly 2,300 people across hotel, marine, and engineering departments. Working on the world's largest cruise ship means a small-city work environment — multiple restaurants, theatres, casinos, retail. Marine and engineering officers value the consistent build standard across the Oasis series; cross-training between sister ships is fast. Hotel staff face the cruise industry's most intense passenger-density workload but on what is arguably its most coherent platform.
