Last November, on the monday after the Food and Wine festival ended, as well as the Festival of Masters, Epcot was a total ghost town. You could walk around and not see anyone, it was creepy.
While waiting for my fiance to finish up in the restroom, we were watching the entrance to Spaceship Earth. There seemed to be no one entering or exiting, so we thought the ride was closed. We went to check it out after, and ended up with just me, my fiance and my mom and sister on the ride. It was really cool.
