I took this unique shot of the exterior of Carousel of Progress a few weeks ago. The doors on the left are at the exit, while the doors on the right open to the attraction's entrance. The interesting thing is that there are "new" sets of doors in these positions every five minutes. The Carousel of Progress consists of six theaters that hold 240 guests in each. The theaters rotate around a circular stage at the center that is divided into 6 different scenes. The first and last scenes involve the loading and unloading of guests, as seen in this photograph. Debuting at the 1964 New York World's Fair, the Carousel of Progress is the longest running stage show, with the most performances, in the history of American theater. It was located in Disneyland from 1967 to 1973 before being moved to the Magic Kingdom. As a Disney nostalgic, this is one of my favorites. It is one of the only attractions in all of Walt Disney World to have been touched by Walt Disney himself.
