hope they are short adults! I'm 6'2" and recently stayed in the bunk beds at WL (which I am relatively certain are the same size as the bunk beds in the cabins, I didn't sleep on the bunk beds when i stayed at the cabins) The bunk beds are located in the bedroom. There is also a very nice murphy bed (folds out of the wall, full size i believe) a couch that will sleep a college kid who's used to crappy beds. and then theres a full/queen sized bed in the master bedroom.
Full kitched (yes FULL, oven and full sized refrigerator included) So if you want to take advantage of that and go food shopping don't go shopping at the goodings/albertons (forget what it is now) at Crossroads (the shopping center just outside of the partner hotels/downtown disney) it is owned by disney and the prices reflect it, just down the road there is a publix with sane prices. Also the prices at Ft Wilderness general store are *slightly* fixed.
The bus transportation wasn't too bad (though it was right outside our window so we could sit and watch TV till the bus came and then run out and catch it. This was back in the chip and dale days so i'm not sure if its gotten better or worse but we never had problems making connections or whatever.
They do cram a lot of the cabins (which incase you hadn't picked up are double wide trailers, yes it fits in the with the wilderness/podunk theming, all you need is a Cops crew and it would be completely authentic) in a small area, so you're really close to your neighbor, which makes dining al fresco a bit uncomfortable
Overall a great place to stay, second only to the Wilderness Lodge (but that was never in contention)
