Grayton Beach is the pits!!! Don't go there around Thanksgiving!!! Top Sail, Henderson are far better choices.
But seriously, it is GREAT. I only said that to discourage people from making reservations. We're planning a stay over Thanksgiving, but am waiting for my DSL to get off her dear ars and confirm plans. We prefer the old loop and it's privacy. But we have a B and the smaller sites are not a problem.
