My wife and I stayed two nights in mid-September at a prime lean-to site.
What we liked most:
Privacy (the sites are mostly spread out, with very limited direct sight lines into the sites around you);
Quiet (quiet hours are 10pm-7am, but the campground was virtually silent all throughout our stay)
Staff (Tiffany and others were welcoming and attentive)
What may be off-putting to others (but we didn't mind):
Few amenities;
Some minor cosmetic issues in the restrooms (facilities were clean and stocked, but some paint chipping and wear was evident);
The prime sites have some impressive views, but most of the other sites are quite modest sized spaces cleared out in the woods
