I don't know how long your trip is going to be, but I would go to some of the resorts just to see the decorations then go eat. After you eat your lunch go back relas unpack and rest for alittle while then head back to epcot. I think if you don't go and see some of the decorations when you first get there I don't think you will later in your trip. I went down for Christmas 05 and missed some of the resort deco's and I wished that I didi it sooner rather than try to do it later.
