Probably would be the same as GA camping, but with the ability to make a camp fire (in 100 degree nights YEAH RIGHT). KoA is not primitive camping by any means, and there is little privacy except in a cabin.
I stayed there the Wednesday prior in 2005 (?) and it was your typical KOA, except right outside Roo. Nice place, but they've gotten wild with the pricing in recent years and like someone said up thread, I've heard that the vendors have been taking the place over in recent years.
