A Tour Of The World's Biggest Cruise Ship (VIDEO)

With 21 swimming pools, 24 restaurants and its own version of New York City's Central Park, this $1.5 billion cruise ship's 5,400 passengers should have plenty to do.

Royal Caribbean's "Oasis Of The Seas," the world's most massive luxury cruise liner, dwarfs the second-largest ship, the Queen Mary II, by 50 percent at 16 decks high and weighing in at 220,000 gross tons.

What does it take to stock a ship this size? Ten thousand rolls of toilet paper, for starters.
