Christmas time at WDW! I just went 11/28 to 12/3 (the Monday through Sat. after Thanksgiving) and it was CHRISTMAS OVERLOAD! I loved every minute of it especially since the crowds were SO low! Honestly, the longest I waited for any ride was 10 minutes for Space Mountain. I rode TOT about 7 times in a row with no wait. Same with Splash Mountain. Even Soarin' was a walk-on for me, and I had heard horror stories from people going prior to 11/28 - apparently people needed fastpasses and STILL waited approx. 30 minutes for the ride.
I've heard that the following week was filled with POP Warner kids, which is an annual event, so I would avoid that week if you can. I understand that their crowd isn't felt in the parks as much, but that they are ALL OVER the value and some mod. resorts.
Happy Planning! If you have any other questions, feel free to PM me.
