But if you have a lot of money you don't have to bother with the bugs and the riff-raff at the campground, you can overnight in a B&B[1]! Make sure you bring your dinner jacket though. They even provide a private ferry from Fernandina Beach, FL, so no risk of accidentally touching any smelly campers.
