Hi, Johnny. Maybe I can contribute a few facts about the campground.
The Rv Park is operated by the State of Georgia, matter of fact the entire Island is a State owned piece of real estate. Costs you a pittance to enter though.
Rhe park is at the nortern end and is quite large with more trees than you con count. It is like being in a forest. Full hookup on most sites, (Can't remember if they have cable, I don't think so).
We were there in May/06 for 3 days and explored the whole island. Transportation like aToad or cycles are a must, if you leave your rig hooked up.
