Get the CityPass and you'll save on the major attractions: World of Coke, CNN, GA Aquarium and more. I'd suggest checking out Stone Mountain and SFoG if you have time. The Braves opened a new stadium this year if you're into sports. If you're traveling by car, I recommend a stop at Lake Winnepesaukah in Chatanooga - a traditional style amusement park with some older style classic rides you can't find anywhere else.
