Just throwing this out to put in the mix.
They have a few cabins and amble camping space, bonfire scene nightly. Very eclectic mix of bikes and riders.

1hour 14 minutes to Back of the Dragon, but I'd take a longer less direct route....

I've stayed there several times and always had a good experience. The number of cabins and availability might be the limiting factor for our group.
Regardless of where to stay, another ride near Back of the Dragon (Marion to Tazwell, VA) that I don't think has been mentioned is the Devil's Thumbprint at Burkes Garden, not far from Tazwell (top of Back of the Dragon).
