Cruise ships just keep on getting bigger, more luxurious, and oh so grand. Royal Caribbean is upping the cruise ship line ante with its Oasis of the Seas cruise ship which is expected to enter service in December of 2009.

A recent press release is posted below.
=====================================================
Steeped in a philosophy that innovation and imagination contribute to a remarkable cruise vacation, Royal Caribbean has once again raised the bar with the announcement of the latest amenities on its newest ship, Oasis of the Seas. Launching in late 2009, Oasis of the Seas will be the world’s largest and most revolutionary ship introducing the cruise line’s new neighborhood concept, which will provide vacationers with the opportunity to seek out relevant experiences based on their personal styles, preferences or moods. Boardwalk, will be a breathtaking space for families inspired by the nostalgic seaside piers of yesteryear; the first amphitheater at sea, AquaTheater, will celebrate water with the largest freshwater pool found on a ship offering a full spectrum of activities and performances for guests; and the urban living concept will take to the high seas with the introduction of industry-first loft suites offering expansive ocean views and luxury amenities.

Enhancements to the cruise line’s signature Royal Promenade will include a new design allowing guests to have a physical connection with the neighborhood above, Central Park, as natural light cascades down from the sky through the Crystal Canopy sculptured glass domes. Other surprises include two rock-climbing walls and the first zip-line at sea suspended nine decks above Boardwalk.
