We stayed in the tent only area and it was nice.  I don't remember a lot of road noise but then we traveled 2 weeks around Florida and heard road noise in every park so maybe I was Immune to it.  The bath house in at the swimming beach and it is a little walk, so if you have little ones that might be a pain.  Also in the summer I can imagine it would be packed with day use visitors.  We checked in late so no interactions with any Park staff but the lady that booked the site on the phone was nice.  Park is close to Jekyll Island where there are killer bike paths all around the island and that is what we were there for.  The camp ground on Jekyll did not look good.  I would return and stay here.
