Greenbrier has a couple of very small cabin-type rentals. They also have an RV already set up at the campground that they lease. There are 2 large "his" and "her" tents that are very large and can accommodate a few people (3 or 4, I think).
They have a few cabins and you can also rent a tent set up. There was a cabin by walkway to beach
Call pioneer cabin rentals, they have cabins all around the area
Did not see any sorry but we stayed there in November and loved the place
