Your post is very timely and you are a big help. We are going to Fort Pickens (spent Easter there and absolutely loved it) this summer and can't get the first night so I spent a lot of time last night looking for a campground for the first night. Your Gunter Hill could be a good stop. I've looked and it's available. We also like Guntersville further north in AL but it's pretty far off the route and requires two night reservations on a weekend.
