Any one of those would be a good spot. We prefer Huntington Beach as the new section is all full hookups and some of the old section is also. The attractions for us are the bird watching, beach combing and the amount we can bicycle without leaving the park. New section is less spacious but not badly done. Old section is roomier but more rustic. We are SC seniors so it costs very little to camp in our state parks and we have enjoyed many of them. Lake Greenwood is another beautiful park although not at the beach. Enjoy your trip!
