Oakplantation vs Mt. Pleasant KOA in Charleston, SC

I have stayed at Mt. P and it is OK. Prefer state and county parks when I can get them. We have stayed at James Island County Park for years. It is our favorite. All the amenities of KOA except not commercial. It is close to services like Mal Wart and restaurants but far enough in the woods to be quiet. There are two water parks for guests and a fishing dock. Miles of paved bike/walking trails. Commuting to Daniel Is is probably easier from James too. Have a great trip no matter where you pick!
