We have camped there. It not too bad on a non holiday weekend. I sent you a PM snow, Don't get a supersite, there is nothing super about them, Friends of ours had one and they had no room between campers. Its golf cart heaven there, but at 11pm it all gets pretty quiet. Since they put in the water park the rates have gone way up, so we stopped going.
This is the way the sites are setup, During the Oyster festival they pack em in. The space in front of our 5th is another site during the festival, At other times they keep it empty. THe people in the hybrid behind us we were camping with.
