You might want to consider Davis Bayou Campground which is part of Gulf Shores National Seashore. You can reserve a site thru recreation.gov. It is a secluded quiet place in Ocean Springs, Ms (just east of Biloxi on US90). If you have the national park access pass (senior pass), camping fee is $11 per night for a 50 amp site. There is a dump station but no sewer at each site. The bathhouse is kept very clean with each shower having its own entrance from the outside. I just stayed there at the first of December and will go back if I am in that area. There is a great visitor center and lots of wildlife. Ten minute drive to Biloxi. Great park ranger and park host on site. If you like to walk, drive and park at the end of the US90 bridge to Biloxi and walk to Biloxi (Golden Nugget ) and back. That is a 5k walk/run with the beautiful view at the top of the bridge.
