A second vote for Betty's in Abbeville. Be forewarned, it is a bit different. Betty essentially graveled over her smallish back/side yards to allow for RV parking. It's tight, and has no amenities except hookups. Forget about kid activities, or even dog parks (dogs are happily permitted, just that the "CG" is really small!).
BUT - Betty also has an expansive covered patio, in which campers are almost required to attend the nightly "Happy Hour" - BYOB, and light snacks/appetizers. This is socializing, not a drinking party. Everyone chats about what they did during the day, places they found, where they ate, etc. Betty will very frequently host or organize tours and field trips to local events/attractions, based on the group discussion of the evening before. Or the campers may decide to have an impromptu crawfish boil the next night on site. Sometimes there's music, either by the campers themselves, or a local friend stops by. It's as close to being invited to stay at someone's house as you can get!
