As I write this, Royal Carribean cruise lines is building a vessels that, when complete, will be the size of the Queen Elizabeth and QEII combined.
That ship is called "Oasis Of The Seas" and at $1.24 billion is the largest and most expensive vehicle of its kind, if not of any kind, ever made. According to WallStreetFighter, Genesis will be 1,180 feet long, 220,000 tons and able to carry 6,400 passengers and 2,100 crew members.
All I can say is "wow. The ship is divided into neighborhoods such that "Central Park" is the main middle "place to be" with luxury restaurants and shops.
The first trip of this new "Wonder of the World" will be December 9th, 2009.
