Tim,
If you find yourself in the Charleston/Isle of Palms area forget Wild Dunes and go play Patriots Point. Before a misguided management company decided to sink many millions into it to make it lush and attractive to tourists, it was about the fastest, funnest course one could imagine on this side of the Pond. Still, they didn't manage to ruin it.
There is nothing at Wild Dunes that can compare to the back nine at Patriots Point, especially if playing late afternoon/early evening.
