Wonder of the Seas set sail on Friday for voyage to the Caribbean

The 362-m long Royal Caribbean liner carries 6,988 passengers and 2,300 crew

Social media users have described the cruise ship as a 'city on the water' online

The ship has 18 decks - 16 for passengers and cost more than £1billion to make

She is a true behemoth of the ocean; a city on water longer than the Shard is tall with her own Central Park, ice rink, casino, 19 swimming pools, 20 restaurants and 11 bars.

Weighing in at 236,857 tons – five times that of the Titanic – the Wonder of the Seas, the world's biggest cruise ship, set sail in spectacular style on Friday for her maiden seven-day voyage from Fort Lauderdale, Florida, to the Caribbean.
