We go to Myrtle Beach several times in the summer but don't camp because we have a house there. I did drive thru Ocean Lakes last year just to check it out. It was middle of summer and it did look over-crowded..... I don't mind a busy, full cg but OL looked like a cluster to me.
In North Myrtle beach they have gotten very strict on the golf carts but some cg's don't monitor the golf cart rules very well at all. Word got out that the cart would be taken immediately if the age and speed rules were broken it would spread fast, and no refund if your under age kid gets caught. I saw this a lot at Beth Page, young kids flying around but they don't play now, they'll get ya.
I leave for Myrtle Beach tomorrow morning!
