capcrn2009,
I saw your thread about this and it sounds like a plan.
The one thing I'm not certain of is if Publix delivers groceries. If so that's news to me. Most people open an account with
http://www.gardengrocer.com (people seem to use them frequently who are in the cabins). You sign up for your order/selections before you leave and they will bring it to you.
Since you won't have wheels, another consideration is to order pizza and have it delivered. They offer a take-out pizza at Trail's End but it generally does not have a very good reputation. I call the nearest Papa John's at 407-477-7777 in Lake Buena Vista. Our crew usually gets 2 large "the works". They deliver to the Fort check-in office building. Sometimes they have specials so always ask. And always properly tip your driver.
On the night we check in we always get a take-out dinner from Trails End called the "Giddyup and Go" (or GAG as it is otherwise known). It has 10 pieces of fried chicken (pretty good), choice of 2 sides (slaw, mashed taters, pork-n-beans, fries, mach/cheese) and biscuits. Plus they provide paper plates, napkins, plastic knife-fork-spoon, salt/pepper, etc. It costs $24 but it will feed a family of 4 easily (drinks are extra naturally).
I love your plan.
Good luck!

PS - saw a Papa Johns pizza commercial on NBC tonight "any pizza for $11"
