You might want to post this question to those on the camping forum.
We have stayed at FW on many occassions. We find it a very relaxing resort where we can escape the hectic parks. Though many have had things to say about the transportation we have never had a problem with it. In fact the last few times we went I dont think we waited more then 10 minutes. Do take into consideration that in the mornings it will be busy because everyone is doing the same thing you are, so give yourself a little extra time. We always alot ourselves an hour to go anywhere on property.
Some do like the convenience of the golf carts but they can get expensive. If you decide to do that you need to call the bike barn now to reserve a cart. Many bring bikes along, especially for the children.
When planning meals think fast and easy. I wouldnt do anything that requires alot of prep work. There is a grill provided on the deck of your cabin. This is a great place to sit out and just enjoy the atmosphere. You might want to get some marshmellows or do smores.
