Any of the A loop sites have plenty of level grass for a tent. They also have level gravel drives if you end up with a camper by then. A-48 would be a good one. It has a circle pull through drive and a lot of grass area. It is 4 sites down from all the action at A-44. Maybe 75 yards to A-44. So close enough for easy walk to meals and gatherings but still far enough away to get some sleep if you decide to crash before the party crowd.
