I don't know. I've been trying to poll this on all the DISers for the past couple of months because we're gonna be there from Saturday the 3rd through Tuesday the 6th. I'm thinking that it probably will be just because New Years day is so close to the weekend that people will just stay throughout the whole time. But who knows, the economy isn't doing too good, traveling is hard because of the weather, and people might have to go back home for work. I'm crossing my fingers for lighter crowds, but I'm preparing myself for hell. Thats why we're staying while the decorations are going down; because people won't be there and we can hit all the stuff we missed that is non-Christmas oriented on those days while we focus on the big stuff on Saturday and Sunday.
I say, if you really wanna see the decor before they take it down, GO FOR IT. The Christmas spirit is all around while its up and it would be a shame to miss !
