Gary,
The key to getting into Fort Wilderness is never give up trying! I bought my Newell from a man who loved to stay at DisneyWorld and his wife told me about how to get in. Call them everyday or twice a day; they have cancellations all of the time. If you can get a space for 1 or 2 nights take it; then keep calling for the additional days that you want to stay. Believe me this works because people are cancelling reservations all the time and Disney does not use a waiting list.
