The fifth giant Oasis-class ship has been handed over to Royal Caribbean International ahead of entering into service in the spring.
Wonder of the Seas took three years to build and is due to make its debut sailing from Fort Lauderdale in Florida on March 4 for a series of seven-night Caribbean sailings.
The vessel, capable of carrying almost 7,000 passengers and 2,300 crew, will then reposition to the Mediterranean for the summer to run sailings from Barcelona and Civitavecchia, the port of Rome.
The company took delivery of the ship in Marseille with French with shipyard partner Chantiers de l’Atlantique.
Royal Caribbean Group president and chief executive Jason Liberty said: “Wonder of the Seas will energise cruising in a bolder and bigger way.
“Adding this ship to our already best-in-class fleet elevates the company in continuing to lead the industry with new features and innovation.
“This is one more way that we’re delivering world-class and memorable vacations, responsibly, to guests around the world.”
Royal Caribbean International president and chief executive Michael Bayley added: “Along with taking the revolutionary Oasis Class ships to a new level of wonder, innovation and adventure, Wonder sets the stage for the spring and summer vacations families and all travellers alike are looking forward to in the new year.
“The combination of brand-new features and favourites that span thrills, entertainment, dining and nightlife is unparalleled, and it’s what will make our latest and most innovative ship the world’s newest wonder and the ultimate vacation in the Caribbean and Europe.”
