Disney World is actually the second floor of a massive system of underground tunnels.
"Its full name is the Utilidor," he said. "It's a series of corridors that allow cast members to work behind the scenes and not disrupt the show on-stage. It's actually kind of boring in some places and it's creepy in others. That being said there are some aspects that are unique. The Automatic Vacuum Assisted Collection System is a series of tubes that connect all of the restaurants to the central dump that's behind Splash Mountain. That way the smelly trash can travel secretly below without people seeing it. 7 of the old attractions (like It's a Small World and the Country Bear Jamboree) are still run from the Utilidor. In addition, there are 2 restaurants, a barber shop and offices down there."
