One night stop overs in GA are the norm for me and this place is perfect!  LOTS of tree's, Dog friendly and easy to get around.  Right off the highway.  Clean bathhouse with lots of hot water.  Small lakes with trails, bench's and open spaces makes it a great place to stop over.  Very tame rabbits everywhere, will come right up into your lap (not MINE, but watched them do it with others).  Concrete pads and wood tables built for wheel chairs or your own chair at the ends.  Easy and fast check in on the phone.  Quite.  

Didn't use the dump station or sewer hookup.

Blue Spring State Park in Orange City, FL.  Visited mid-Sept 2019 middle of the week.  Although the campground was mostly booked we found space, with no crowds at the spring or the river.  Rent a tub and float down, with no crowds it's a 4 min walk up and a 15 min float down. The manatee's are on the move with their calfs.  The love bugs are brutal this time of year, but the campground is separated enough from the river area to feel safe from gators with your dogs.  Great short trail from campground to main area which included shop, food, tables and of course wood walkways by the river.   Walkways wide enough for wheelchairs.  Dogs allowed all over park except the wood trail up to the spring head.  New bathrooms, 2 bars on the cell service and I did see laundry available.
