As I understand, the Christmas decorations start going up Nov. 1. I think some or all of the Christmas activities start some time in mid-Nov., like around the 13th or so. My family and I are going 11/25/07 - 12/2/07. We have already checked and were told that all of the Christmas events, etc. would be happening then. We were told by Disney that the week right after Thanksgiving is the best time crowd-wise to go to be able to see Christmas.
