Not sure the days you are talking about, but we've been 3 times the week of Thanksgiving, doing the parks Mon-Friday of that week. The first year was OK- with Monday through Wednesday being managable but Thursday and Friday were a zoo. The next trip was right after 9/11 so it was wonderful- no crowds! Last year was crowded compared to the first two trips. We were very surprised by the crowds at the beginning of the week. MK was packed by lunch every day. A CM told us Thanksgiving week was getting more and more crowded every year and this year proved it to us. It is managable if you plan right though. Thanksgiving Day at MK is always a zoo. The weekends I have heard are a zoo. We did EE most days and skipped to another park by lunch- when the EE park was really packed. We have been to WDW 3 times before and really read these boards so we knew how to plan- what rides we liked and didn't, which ones to head to first, etc. We used Fastpass the entire time and this was a lifesaver- would have never gotton everything done without them. This is a magical time of year to go- Christmas decorations up, and who can beat Thanksgiving in WDW with your family? However, after 3 trips during this time, we are going to try early December this year and hope for better crowds.
