We like to go one of the first two weeks of December as all the Christmas decorations are up by the beginning of the month. But keep in mind the first two weeks of December are the lowest points for DVC members so a lot of us are there at that time. Still seems like crowds aren't too bad though. You will love it during the Christmas season. It is wonderful. Make sure to check out a bunch of the resorts for some great decorations, trees and even a huge real gingerbread house inside the Grand Floridian resort. I can smell it now.........MMMMMMM!
