WE camped here in 2018 winter and had a very good time.  Other than February and if you are older than 55 or so you must move out after 2 weeks and sometimes if enough sites you can move to another site.  In February they allow 4 weeks stay.  Some sites are very level and some not so much, some smaller and some bigger.  Pretty nice staff at the store and check in.  The beach is gorgeous and a walk from campsites.  Lots of great restaurants down the road and across the street is the Brookgreen Gardens which is a wonderful place to walk around and admire the plantings,  there is wildlife area and you can take a ride up the river and see how life was back in the day.  WONDERFUL place.
