In Disney theme parks, the utilidor system is a system of some of the world's largest utility tunnels, mainly for Walt Disney World's Magic Kingdom in Florida. The utilidors, short for utility corridors, are a part of Disney's "backstage" (behind-the-scenes) area. They allow Disney employees to perform park support operations, such as trash removal, and for costumed characters to quickly reach their destinations on the surface out of the sight of guests to avoid ruining the illusion that is being created.
