I have 2 friends who are travel agents who primarily do Disney reservations. Both love Fort Wilderness. I talk about them in this article on
Fort Wilderness.

I do know that Jason is attempting to make a go at being a fulltime travel agent and has pulled off some miracles for us in the past.
As for options outside of Disney. There are quite a few but none have shuttles to Disney. I think the most convenient to public transportation is Sherwood Forest. It's an OK park but definitely not my favorite. For Disney, my favorite would be Tropical Palms but I don't know about public transportation options from there.
I have a list of park options here:
