We were also there the day after Thanksgiving until Dec 4. We went to Epcot on Saturday and MK on Sunday. Both were very manageable. The rest of the week was okay as well. I wouldn't describe it as low crowds. I have been in Sept, the week after Labor Day, and that is low crowds! We did use fast pass because I refuse to stand in any line longer than 15 minutes!! We would get a fast pass then stand in another line, get a drink, bathroom break and it would be time to use the pass. We never felt like we were just standing in line.
