Built in 1971, MK is the world's most visited theme park in the world. Current attendance is 20m+ every year, and rising! MK was built on a man-made hill, allowing Cast Members (CMs) and VIP guests to move unseen via underground tunnels. MK is comprised of six Lands: Main Street U.S.A, AdventureLand, FrontierLand, Liberty Square, TomorrowLand and FrontierLand.
