Disney utilidor system
（重定向自Utilidor）
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 ("cast members") to perform park support operations, such as trash removal, out of the sight of guests to avoid ruining the illusion that is being created.
