I am staying at Red Gate Campground next month, don't know much about it, but chose it because my SIL is in a wedding at the plantation house there at Red Gate Farms and it will be convenient for my babysitting/dog sitting responsibilities. DD & SIL are letting me keep their dog, since hotel doesn't allow and dog doesn't board well. I also get to keep Granddaughter when her mom and dad have wedding duties.
I stayed at Ft McAllister State Park last year and while it was a bit further out, it was still a great place. We chose Ft McAllister over Skidaway, because they were working on the sites at that time and would not have water for a couple of the days I planned to be there.
