Many campgrounds are located bay side rather than ocean side. However, the hike to the ocean side is usually very short and worth the effort. Ft Pickens at Pensacola is such a place. Coastline at Eastpoint/Apalachicola faces the bay with St George island in front of it. No beach, just a rock rip-rap shore line and a pier to fish off of, However, an extremely nice park and view. Again, St George is a close drive away.
Attached pics were taken from highway 98 a mile and a half east of Coastline RV park.
I highly recommend Ft Pickens, and if you are a senior with the Interagency senior pass, you don't have to pay the $16 entrance fee (good for a week) and campsites are half price, but its worth it in any case. Be aware, the sites are power/water with a dump station, and showers and restrooms, no sewer. Don't know what kind of rig the OP has, but stay away from loops B and D except in a tent or small popup. Short, small sites with lots of limbs and trees. Ft Pickens now is on Google street view with complete drive thru of the loops (except for B and D (I bet the camera was too tall on the Google car)).
