Sorry you haven't had any responses yet. The Florida group is spread pretty thin these days.
I have no direct experience with the campgrounds around NSB. I checked the reviews last year when we were thinking about going to the airfest at the airport over there. As it turned out, we didn't go. There are three campgrounds all within a mile of each other on the same road. Of the three, New Smyrna Beach CG seems to have an edge on getting the better reviews. From Google Earth, their park seems to be a bit better organized.
Maybe someone who has been to one or more of these parks will post their experience. Whatever your choice, I'm sure you'll have a good time.
Please give our regards to Sylvia.
