Walt Disney World®, the world's biggest amusement park, is a self-contained city, covering an area twice the size of New York's Manhattan. Four main parks comprise the bulk of Walt Disney World®—Magic Kingdom, Epcot, Disney’s Hollywood Studios®, and Disney’s Animal Kingdom®—each with its own themed areas, shows, rides, and attractions. More than 50 million visitors pass through the gates each year into the self-proclaimed “Happiest Place on Earth” and home of Mickey Mouse.
