We are heading to WDW The week of Thanksgiving....we'll be there Sunday-Friday November 19-24. I was hoping we might see some Holiday decor.....but seeing the schedule for MVMCP made me think we might miss it altogether....disappointing!!
A couple years ago, I went the weekend before Thanksgiving and I think most everything was up. It was just the activities-MVMCP, Holiday Storytellers, CP, that hadn't started yet.
You will see lots of decorations up, particularly at the resorts. They usually start to go up in mid-November. One year, we stayed at the Board Walk Inn around that time of year; we went to bed one night and woke up to find the whole place completely done! Tree, lights, EVERYTHING. We were stunned -- and enchanted.
