Atlanta vacation-world of coke and georgia aquarium?

We are going on vacation to Atlanta and have 1 day to see the Aquarium AND the World of Coke. Are these close enough together to park in the parking garage and walk to each? Or is there a bus/shuttle that takes you to both? Also, is 1 day enough time to see both?

They are literally right next door to one another. Simple walking distance.
You won’t have any problems seeing them both in one day. The Aquarium is only about a 3 hour tour and Coke will take even less time than that. Have lunch in between the tours.
They are pretty much next to each other, even share a parking garage. I would say you could definately see both in the same day, but I would hit the aquarium first thing in the morning, because the later in the day it gets the busier it gets, then head over to the World of Coca-Cola.
