Atlanta, GA

My wife and I went there for our 5th anniversary. They have an Atlanta 'city pass' that's like $75/person. It gives you tickets to CNN tower, Zoo, Aquarium, Modern History Museum & World of Coke. It's a pretty good deal. If you're going to stay out there, I suggest the Marriott. It's setup a lot like a Vegas hotel. The ground level is very active. They have local restaurants show up every week and you can try a bunch of stuff for free. It's a good deal. Oh, I found the website for it.

We stayed at the Hilton, which is kind of next door. It's attached via an elevated walkway. The Hilton is set up for like... 65+ y/o travelers. Where as the Marriott is pretty cool. And it's HUGE. I suggest that one. Stay downtown. You can walk almost everywhere. We took 2-3 uber's the entire trip (Zoo, Museum & Kevin Rathbun Steak). It was a great trip.

World of Coke & Aquarium are right next to each other. And you can go through coke in ~1 hour, including trying all of the various types of soda from around the world.

The zoo is a bit further away. The aquarium itself is big (it has this giant tank with 3 whale sharks), but aside from that center tank, it's lacking. A few smaller exhibits around the perimeter, but the big draw is the whale sharks. My wife liked it, but I was underwhelmed after growing up taking trips to Baltimore for their much less volume of water, but way better thought out aquarium.

At coke, they had this guy in a big Coke polar bear costume with 1 false arm so he could use that arm and fingers to make the mouth open and eyes blink and shit. It was a pretty badass costume.

Oh, I found it! This is from when I went there almost 6 years ago.

I don't recall seeing any security while I was there. Just the tour guide (girl). And you walk behind glass as the people do their bullshit on the other side of that glass.
