The big problem with Fort Wilderness is the reservation policy and of course its popularity. You can reserve as much as you want for almost no deposit(usually one night) then change it or cancel 5 days out for no fees.
There are travel agencies that specialize in the Fort. They will watch for you and make the reservations when they open up. Wishuponastarwithus, dreamsunlimitedtravel or mousefantravel are a few that are out there. Do some research on the web and go from there. The agencies usually don't charge you anything above the rates for the park.
