The number one thing we wanted to do was visit The World of Coca-Cola when we got to Atlanta. I had once thought it was factory you got to tour, but it really is just a tourist spot. I really doubt any serious production goes on in these walls. This place was built just for tours and get people excited about drinking Coca-Cola.
We luckily got the Atlanta CityPass (most major cities have this program) which allows us to see this place among several others for much less than what they'd be all together. We got it online and we got the official booklet at the ticket booth here.
Ahead of us was a HUGE middle school class field trip. The first three stops at this place are "grouped" so we didn't have to be around them per se, but it was like a zombie movie. I tried to give them enough time to be ahead of us as possible and it was still was a problem once the tour got the point where you walked to whatever you wanted to see next.
