We stayed at the cabins in December. It was okay. We prefer other deluxes, but, if we have a 3rd child, I imagine we'll be spending our fair share of visits at FW cabins in the future. My 4-year-old liked it very much, but we combined it with a stay at AKL and that is where his heart is.
As everyone says, transportation was abysmal. We rented a car for the parks, but getting to MK was a pain any way you sliced it. We wouldn't spend the money for a golf cart. That is a waste of dollars to us, dollars that could be better served at a monorail resort.
Our cabin was pretty dirty and rundown (moldy, floors that remained black with dirt no matter how many times I scrubbed, a dishwasher that leaked), but the extra space was nice. I liked the setting, so peaceful, and our mousekeeper did her part to add Disney magic with several towel animals.
The pool is a big concrete rectangle. The beach/marina area was fun with a petting zoo and that is where Trails End and HDDR are. Unofrtuantely, we didn't make it to the campfire so I can't comment.
Give it a try, I say! Have fun.
