We went the last week in September 2002. I think that the longest we waited in a line was about 20 minutes, and I'm pretty sure that the CM's laughed at us when we tried to use the Fastpass system! I considered the park to be not very crowded that week, and there was only one line where my then-3-year-old got restless while waiting. We had the ability to do our favorite rides so many times that by the last day I was more than willing to sit for three hours to save our space for Fantasmic. (A mistake--I wasn't aggressive enough and got shuffled off to the side by encroaching crowds.) The only time we actually needed to use a fastpass was for the Haunted Mansion, which was closed until Friday for their holiday makeover, and had a special grand opening-type thing that made it very crowded. We experienced heavier crowds on Friday than on any other day of the week. Also, we still had to stand in line to get character autographs, the longest being for Mickey at his house in Toontown, and I'd say that wasn't more than 20 minutes, either. The down side to going at that time of year is that many rides were closed, and there wasn't a single Early Entry day while we were there. But who needs early entry if the crowds are that low, right?
