We have been twice on Thanksgiving(2011,2013) and it has not been bad. We go early, and 1st trip had dinner at 1900 PF and came back in for fireworks - crowded, but not bad. Last trip we set up lunch at Liberty Tree so we could leave later and hop to HS for Osbourne lights if we wanted, but got MSEP FP so stayed. Black Friday was actually a lot worse there - we had PPO brft. at CP and took pics on fairly empty Main St., and when we came out, Main Street was mobbed with crowds coming in at opening - took a photo for the before and after comparison. That was he most crowded I had seen it right at opening in any of our trips. I think some people figure Thanksgiving will be crowded and opt for the day after. If you can go early and have it well planned you will be fine.
