I have a feeling that this new resort, be it DVC or not, will have to have some sort of name unto itself. The "Villas at Fort Wilderness" would end up being a disaster as far as reservations goes. How many people have been given (or tried to be given) a ressie at Wilderness Lodge because the people at reservations are soooo confused? Since there already is a Villas at Wilderness Lodge, just think what having Villas at Fort Wilderness would do to reservations.
And people who haven't a clue about where they want to stay would be thinking they're booking one resort, but end up with the other.
Would this mean the theme may be different enough from Wilderness Lodge, so people wouldn't be confused? The Old West train depot might just do that. It will be interesting to see......
