Thought I'd post about my experience using fastpasses cause I know I was looking for this info before my trip. I went Friday 11/14. I was staying off site so had to buy 3 days before. I logged in right at 7 am on Tuesday and 7D and tron were already gone. I was able to do multiLL and got haunted mansion for 3:05 to 4:05, winnie the pooh for 3:45 to 4:45, and jingle cruise for 4:40 to 5:40. I only had the party tickets in my account and no other tickets. I was happy to get jingle cruise cause that line stayed pretty solid all night.

I have done the xmas party a few times in years past and I felt like this party was more crowded and the waits were higher than in the past. We still got to do what we wanted with smart planning and being willing to walk fast, but we weren't doing the party specific stuff like parades or characters and we were just 2 adults. The walkways were insanely crowded and we purposely stayed out of the hub entirely.
