The pic in my sig was taken in the ToT queue two weeks after 9/11. Talk about empty. There weren't even people waiting for us to take the pic. Just no one in line. Although we waited for nothing, I prefer some crowds. People make the shows a lot more fun. But going in September will certainly give you the feel of being there alone. This past September we experienced far more crowds than the last few years, but we still love it. One time we were talking with some fellow Disers after MK closed, and were asked by a castmember if we were needing anything, because the park was closed was we needed to be heading out. I was a little embarrassed to be asked to leave. There were many people behind us, so I am not sure why we were asked to leave. I guess that castmember didn't get the memo. She was nice, but firm.
Anyway, enjoy November.
