There is an I95 website that has alot of info:
http://www.usastar.com/i95/homepage.htm just go to the left where it says lodging, then it will bring you to a page with the states, just click on Georgia. It looks like exit 94 has quite a few places to stay, I am not sure if we have ever stayed at that exact exit (though we probally have), but I usually like to stick to chains that I know and that look clean (if they are not booked up you can always ask to see a room before you registar). I usually go with Holiday Inn Express/Holiday Inns.
