The Oasis of the Seas, the largest cruise liner ever built, has left port for Miami, from where it will begin taking more than 6,000 passengers at time (!!!) on Royal Caribbean tours in December. It cost $1.5 billion to build and is 1,200 feet long-one-and-a-half times the size of the Queen Mary II. Man, just think of all the despair and communicable disease that thing's going to pack in.
