I've never stayed there when it was open before but knew about it. The link above takes you to their webpage, but the facebook page has more info on it.
It looks like the lodge meals are only Sat-Sun right now, but they are looking to expand things for next yr.
I don't camp much; my old back & body doesn't take to it like yrs before, but I would be interested in going there sometime and getting a room in the lodge. I'm guessing you have access to the rooms on weekdays, just no meals served; not clear on this.
Excellent location tho, and in the middle of great roads in the N. Georgia mountains!
