It's mostly rental houses; if it just your immediate family, try to get a smaller house.
We got stuck in the sand, and that is catnip to rednecks, a number of whom came out of their houses to "help" us. After a few sort-of-scary, hold-muh-beer and watch me git ya out, moments, a group of competent guys (still Southern, but I would not classify them as rednecks) in a four wheel drive pickup stopped and got us out in short order. While we were doing that, my wife was invited into a high-class wedding party in a house across the street.
So, I suppose I am saying that there are all types of people there. It's a good place, and like someone else said, the beaches are great.
Do you have something against southern gentlemen?
