Royal Caribbean International announced Wednesday the delivery of its newest cruise ship from Finland's STX Europe, Oasis of the Seas.

Oasis of the Seas is the largest and most revolutionary cruise ship in the world, spanning 16 decks, featuring 2,700 staterooms and able to carry 5,400 guests at double occupancy.

It is the first ship to feature Royal Caribbean's new neighbourhood concept of seven distinct themed areas including Central Park, Boardwalk, the Royal Promenade, the Pool and Sports Zone, Vitality at Sea Spa and Fitness Center, Entertainment Place and Youth Zone.

After nearly six years in the making, Oasis of the Seas finally departed Turku on Friday to make her first transatlantic crossing with Captain William S. Wright.

The crossing has been chronicled daily at OasisoftheSeas.com through webisodes and via Twitter on @OasisandAllure. Visitors to the site will also be able to follow the journey through a Google Maps application and personal updates from Richard Fain's "Chairman's Blog" and CEO Adam Goldstein's "Adam's Blog".

The ship will reach Port Everglades in Fort Lauderdale, Fla. on Wednesday November 11, 2009, her first U.S. debut.

On Friday November 20, Oasis of the Seas will be revealed on ABC's "Good Morning America" and will give viewers an exclusive first glimpse.
