mid-end of Oct. The crowds were a little less than mid March, when we usually go (spring break time). I found there to be a 20-45 minute ride on most rides, except the most popular ones like Test Track, Splash Mountain. I think with the new tax refund, the fairytale pkg, Columbus Day, Canadian Thanksgiving, and the war being over combined, there will be more crowds this coming Oct. We will be there the 10th-20th. It will probably (hopefully!) be better than the summer, though. Weather was gorgeous, with only 1 day of substantial rain and milder temperatures (upper 80's). You will need at least 1 pr of pants, and a sweatjacket. I'll cross my fingers for smaller crowds for both of us!
