Where you are staying I'd highly suggest
Caldonia Golf and Fish Club for a course. It is awsome. For burgers the River City Cafe in Murrels Inlet is hard to beat. It's one of my favorite resturants in the world. I hear Ripleys Aquarium is nice. Dixie Stampeed is my kids favorite, plus my wife was one of the performers so we're a little bias. It's on the north end though but BPS is close by....
