The world's biggest cruise ship, the Oasis of the Seas made its first voyage to Labadee, Haiti on December 1, 2009. To welcome the humongous ship, a new pier as well as a new roller coaster was built on the fabulous beach destination. In the future, Oasis passengers may even get the opportunity to leave the giant ship to visit the nearby Citadelle- the largest fortress in the Western Hemisphere.
