This is all I know of so far at resorts...it's what I have so far on a web page I started where I will have the photos of these things and trip reports when we get back:
While all of the resorts have Christmas trees and other decorations, many of the resorts have special displays too, and lots of them edible, constructed from gingerbread, sugar, and chocolate. To see the decorations at resorts other than the one you are staying in, just hop a resort bus from the TTC or from any of the parks. You could easily spend a whole day resort-hopping to see all of the displays.
If you purchase a gingerbread house from one of the resorts, plan on carrying it home. As far as I know, none of the resorts will ship the houses because of their fragility. If you are flying, make sure to save room in your carryon!
Head for the Contemporary Resort to see a gingerbread village. It's on the fourth floor near Chef Mickey's.
The life-size Gingerbread House at the Grand Floridian Resort, which is also a shop where you can purchase gingerbread houses and gingerbread shingles like the ones that roof the life-size house, stands in the lobby of the hotel. They start making the gingerbread months before they start building to have enough. Every shingle and siding slab is a separate cookie, glued on with decorator icing.
There is an African Village made of modeling chocolate at Boma (a wonderful restaurant serving food buffet-style with an African flavor) at Animal Kingdom Lodge.
Check out Disney's Beach Club Resort lobby for a life-sized completely edible carousel, with sugar horses, giant candy cane poles, and a lighted gingerbread roof! Small gingerbread houses and Christmas stollen will be for sale.
Disney's Boardwalk Resort has a chocolate, sugar, and gingerbread Boardwalk, complete with rides, including a five foot tall Ferris wheel, a carousel, and a water slide. There is even a beach area.
Wilderness Lodge lobby has a huge tree, and also offers a sleigh ride. Like Mickey's Very Merry Christmas Party, the sleigh ride is a ticketed event and to assure a seat, should be booked well in advance.
At Disney's Polynesian Resort, look for an exotic gingerbread village, complete with volcanoes and palm trees. It's on the second floor of the Ceremonial House. You can buy Christmas cookies at the Kona Island coffee bar.
Disney's Yacht Club Resort lobby will have a miniature train winding its way around a sugar mountain and village. Small gingerbread houses, Christmas stollen and Italian pannettone will be sold in the merchandise stores.
