This cruise ship is so large, it could house an entire town

At over 215 feet wide and almost 1,200 feet long, this massive cruise ship is the largest ever built.

For some comparison that's more than triple the length of a football field, end zone to end zone.

Dubbed Harmony of the Seas by its creator, Royal Caribbean, the ship took more than 2 1/2 years to build and cost more than $1 billion.

And watch out, New York City, because Harmony has its own "Central Park" and enough space for nearly 6,800 guests.

And for all of those guests, there are 16 decks, 24 elevators and 23 swimming pools plus plenty of other activities.

Its maiden journey launches May 29, and tickets are still available for upcoming cruises on Harmony. A seven-day cruise going through Spain, France and Italy starts at just over $1,000.
