I've stayed there a number of times, it's my favorite stop near MB. It's got private treed spots, open spots, mostly just water and power, no waste. Central dump site on the way out. I saw a guy catch a four foot shark off the beach last time I was there. Since it's a state park there are nature walks, hiking trails, a big nature display area with both fresh and salt water marshland, the old mansion is there to tour, and there are other attractions nearby, and of course MB five minutes up the road. I've been there in December, so the park was pretty much deserted and very quiet.
