Not much you can add about how this place is awesome, it's one of the best in all of the South. The beach is beautiful, St. Augustine has so many great restaurants and attractions, and the Saturday Farmers/Flea Market at the Amphitheater is amazing.
Tried booking for Labor Day weekend but only tents and a few small camper sites available. For this scheduled Meetup, there are a lot of sites available. Because of the way this park is so spread out, I suggest you try to book in the front loop, sites[masked]. We'll hopefully be able to use the large pavilion again.
More info to come as we get closer to the event.
