We've stayed there a few times when we needed to be in the Raleigh/Durham area. Its convenient, secure, well lit, reasonably priced and easy to get into and out off but its just a place to stay and nothing more. Basically, a large gravel lot with no vegetation; sites are reasonably large and they have full time on-site security. I'd prefer to stay at one of the nearby state parks or state lakes but the gates on these are locked at night (hours vary seasonably) which is a no go if we're there because of family medical issues.
I don't know how crowded it might get on a holiday weekend but we've never seen it more than a 10-15% full. Any event at the nearby equesterian center or fairgrounds might impact occupancy.
