We stayed at Myrtle beach state park years ago and it was very nice. While we were there we checked out Huntington Beach state park in Murrells Inlet just south of there and liked it better. We plan to stop there on the way south this fall.
I looked at that deal for winter months and it is a very good one. The only problem I see is in January the average high temp is only mid fifties and low near freezing. Better than up north but not warm enough for me.
