We stayed in one last August. We loved it! We got it at the 7 month window, after being on the waitlist about 4 days.
The stairs issue for mobility challenged is a consideration, as is the transportation issue. If neither of those is a concern, and you don't mind being "remote" and in the "woods" then I'd give it a try! You may have to waitlist, and you could give yourself xx amount of time on the waitlist before giving up.
