If you're on a quad bike, then I would suggest Kiawah. You can go for miles around the whole course. You may even come across Mario and his gang having some fun. Or you could try the long beaches at either Andy's or Georgie baby's.
If you're only in a buggy it's not much fun as they don't go very fast. Can't pull a handbrake turn as they tend to flip over.
If you're on foot... well, then you're not driving are you!
