I have seen a picture done with the tree at the Wilderness Lodge, and a card done in front of the Ginger bread house at the Grand Floridian. I think anywhere in Disney you can not go wrong. It is just what you and your family like. Have fun making it. I know it will be great!!
There are spots all over that can be good. I think the gingerbread house at the Grand Floridian is good... as is any tree at any of the hotel. Downtown Disney/Marketplace is another. Of course, lots of others will be trying too. There is also other gingerbread at the Beach Club Resort. Its a carousel. Donald's Tree Lot at MK, with Santa... Osbourne Family Lights.....The decorations start going up around mid November. OFL @ MGM start 11/13/06 and the
MVMCP also starts this same date, so decorations should be up or going shortly. We stayed once at Port Orleans Riverside, went to bed and woke the next morning and the tree was up! (was like 11/10)
I enclosed a couple links to site pics to get an idea of a few things. I know I have seen a decorating schedule before, just not this year.
