All you can do is to start calling to find openings. I'd suggest getting two or three spots just in case you don't like the area or park and then you're stuck staying there. Check out the areas for your next year.
Full-Timed for 16 Years .... Back in S&B Again Traveled 8 yr in a 40' 2004 Newmar Dutch Star Motorhome & 8 yr in a 33' Travel Supreme 5th Wheel
We stayed at Bulow RV Resort (nice place with lots of amenities and nice people but I wouldn't consider it a resort) It's located right between St Augustine and Daytona and only a couple miles from Flagler Beach. Also about an hour from Orlando. We stayed there for a few months and decided to move here. https://www.google.com/search?q=bulow+rv&oq=bulow+rv&aqs=chrome..69i57j0l3.14665j0j4&client=ms-android-verizon&sourceid=chrome-mobile&ie=UTF-8
