We are going to be there also!
There are tons of Christmas decorations all throughout the resorts such as a full size(people can walk into it) gingerbread house in the GF! Check out the Osbourne Festival of Lights at the Studios. Also, starting on Novemenber 26, you can do a Candlelight Processional Dinner Package and see the Candlelight Processional while you are there.
Have a great time planning and a great trip!
