The next biggest ship in the world will be Royal Caribbean's Oasis of the Seas, which will make its maiden voyage in December 2009. The $1.5 billion ship accommodates 5,400 passengers. It has seven "neighborhoods," such the Boardwalk, which will feature a carousel, tattoo parlor, and fortune teller. Central Park, a promenade with real grass, will have outdoor cafés and inside cabins with balconies overlooking the action.
