Buccaneer state is nice, but about 20 minutes from Biloxi/Gulfport. Summer is peak "no seeum" season and they seem to be especially thick around there. The back section is close to train tracks and busy with traffic. Personally I like trains, but not everyone does.
If you want to be in the actual Biloxi/Gulfport area with access to all the features, there are several nice commercial campgrounds. Cajun RV is nice. Majestic Oaks gets good reviews too.
