Campground is exactly what it needs to be: a place to land for access to the barrier island beach. I've been there a few times over the last decade, and it's maintained in good shape, tho the poison ivy never retreats. Water supply is good, wash station is useful. Bath houses at national seashore are right nearby. Nothing fancy but they're open so far this year (3rd weekend of May). Campsites are generally small, tho a couple are just cherry. All are exposed: sun, bugs, and sometimes wind. The mosquitos weren't out yet for us, and the little gnats nipped at you, but were manageable. Bring your own comfort - shade and screening.
Nearby, the staff at the cabana are just great. You could spend a lot of time under those shady canopies, sipping something, ducking out of the sun/escaping the bugs for a spell. It's going to be a great season out there, you can feel it.
