We go during the 2nd week of November, and generally this is a wonderfully light time to go. Indeed, it may start filling up on the Friday before Thanksgiving. Overall, this is considered one of the best times to go. And the books and concierge may be able to tell you which parks are emptier on certain days. For example, Magic Kingdom is fabulous on Sunday mornings. Hit the park early, and then go to Crystal Palace for lunch with Pooh and Tigger and the gang. That's what we do. Have fun.
