I returned yesterday (Sunday the 8th). I was there from Thanksgiving on.
I was not shocked by the crowds on Thursday, Thanksgiving day. What shocked me were the crowds the week after. I tend to go the first or second week of December, and this year, the was a significant upswing in crowds during the week.
The weekend after (12/7 - 12/8) was just as bad as the weekend immediately after Thanksgiving.
I was in AK on Saturday(12/7) while waiting for my Boarding Pass for Rise of the Resistance to come up, and the stand by wait time for Everest was posted at 120 minutes. I have never seen it like that.
I was talking with other people one night at WL and they said they were also first week of December peeps, and agreed the crowds were noticeably up this year.
I am hoping it had a lot to do with ROTR. If it is the same next year, I may cut that trip in half, it is losing a lot of its joy.
