If y'all ever come down here (probably for Atlanta, there's not much else that's really touristy), I recommend October or November. Barring summer overstaying or winter coming early, that weather should feel fine for y'all
Also, sunburns don't hurt me. They itch like crazy, but don't hurt at all. Still very unpleasant, but from what I hear about how it affects everyone else, I think I can't out ahead on that one.
