I love that this thread has a good amount of activity! I ran errands for a few hours and came back to 3 pages
Here's my two cents on a few things not that anyone asked 
It depends what you want to do at the party. I don't think we rode any rides during the party last year so I can't tell you about ride wait times. We just didn't have time between waiting in line to meet Aurora, Phillip, Snow White and Snow Prince (we got in line early but got cut off right before their first break so had to wait an extra 15 minutes for them to come back), watching both parades, and Wishes but we also had a 22 month old so we didn't stay until midnight. That said I think the party is worth it just to be able to meet the princes with their princess, the Christmas parade and Holiday Wishes but we are only a family of 3 and our daughter will be free again this year. We also had an ADR for BOG right before and this year we're going to do QS and get in line even earlier and we're going to meet Rapunzel and Eugene instead
I was very worried about the after hours thing doing well and causing the prices of MVMCP to go up A LOT but I was happy to see on the rumors board that they were giving tickets away for free the other day. I agree with you as to why they are waiting to open up the holiday party ticket sales because I'm almost positive they were on sale early in April last year.
Just don't go to MK on AM EMH that week. We were there last year the week before Thanksgiving and touring plans originally had the crowds for MK that day at a 5 but their "what they saw" crowd level was a 10! Luckily, this year that Monday isn't included in FD so maybe it won't be as bad.


I could use some input on MVMCP. the tickets are a ton on money for me and last year I saw quite a few posts that people who went thought a lot of the nights were packed and every year more and more tickets were being sold and it was becoming so crowded that it was not worth the expense. I don't mind spending what for me is a considerable amount of money but not if it's so crowded that it's a waste.

That's the rumor... Honestly I think Disney is seeing how well this after hours thing does before they release the priced for this year's hard tickets events. If they were selling out after hours each time it was offered I would be afraid mnsshp would get hiked way up. With the new discount for after hours for dvc and ap holders, I'm assuming not as many people are shelling out $150 for after hours access.

If you mean the week before Thanksgiving as Nov 12-19, that week is one of the best weeks of the year for lower crowds. The week leading into thanksgiving, Nov 19-26, will be more crowded. I think the week after the holiday after the weekend is over should be a good week too. But I would think of the 2, there's not a clear winner on the better week.
