I have a sort of dissenting opinion on Fort Wilderness cabins. I realize now what I really like about staying on Disney property is the feeling of being in the Disney bubble. Monorails, skyliners, disney dining onsite, etc. While we did really love the cabin itself and the space, it felt very disconnected from Disney. We don't love having to get in our car to get to dining, etc and it didn't feel very pedestrian to us. And a golf cart was rather expensive, if I recall.
It really did feel like cabin camping- not really like Disney. That might be perfect for what you're looking for, but it wasn't for us.
