If you mean New Green Acres located in Walterboro, we overnighted there this past March travelling from Baltimore to Titusville, Fl. The park has mostly pull throughs and ours was sand. The grounds were well kept (no garbage lying about) and the facilities at our site worked. The area is primarily the sandy soil and tall pine mix that you tend to see in the South. They have a pool and a small store on site but we did not use either of them. Access to and from the site was fairly easy, even for a rookie driver in a 39 ft towing.
If you travel with pets, they have a newly converted fenced pet area (used to be a playground) and the owner was very accomodating.
The access road for the grounds is just off the exit from 95 South. From maps and directions, it looked like it may be 'down the road' a bit but it literall is less than 200 feet from the end of the exit road. This is a convience and a detriment as the camp proved to be quite noisy all night from the ongoing traffic on 95.
I would use it again as an overnight spot.
Hope this helps.
