Another thought, is to go during a period of free dining and stay at one of the participating resorts. This is what we have done over Thanksgiving week for the last seven or eight years I realize this may not work with your schedule. I know I would love to camp again at Fort wilderness myself but when I do the math it is cheaper for me to stay at a moderate resort and get the free tableservice dining then to stay at For wilderness and buying a dining plan. Or you could stay at one of the value resorts and then you would get all quick service meals also. Plus you won't have to pull your unit down there and it could be a more relaxing trip that way too.
Thinking outside the box a little bit on this one.
