One of our favorite RV resorts happens to also be in our favorite City, St Augustine FL. Brynn Mawr ocean resort is the premier RV resort in the first coast area. 
The campground is very easy to get into. Our favorite sites are the beach front sites that are on the backside of a sand dunes.
The resort has one very large family friendly pool as well as an adult only pool and hot tub.
All of the beach front sites have elevated porches with picnic tables that offer peeks of the Atlantic ocean and the most beautiful beach on the east coast of Florida 
Cool, looks like you are having fun. I have a sister, lives down that way.
