1. When land-locked Disneyland didn't have enough room for the gigantic show buildings Pirates of the Carbibean and Haunted Mansion required, Walt Disney ordered his people to create the space by excavating under ground. That's why Pirates has the drops and Mansion has the stretching room. The drops in Pirates take you to the underground show space. The stretching room in Mansion is actually an elevator taking you to that attraction's underground show space. At WDW, the stretching room stretches upward and the floor remains at ground level.
2. The WEDway Peoplemover at WDW was the first system to use the linear induction motor (magnets imbedded in the track that push and pull the cars, instead of electric motors on the vehicles). Today, this system is used in Vancouver's SkyTrain and other systems throughout the world. Two other WEDway peoplemover systems were build (the one at WDW is the only one built for a Disney park): one undergound at the airport in Houston, TX and another built underground for Washington, D.C. politicians called the Capital Subway.
