Just let me know when you are planning on being in Atlanta. I think more of the Gone with the wind would be found in Savannah, but I'll be happy to assist in ATL any way I can.
As far as things to see in ATL, it's not a big touristy type town. Travel hub and one of the busiest airports in the world, but not a lot of tourist things.
What type of things are you interested in?
Things I can think of off the top of my head:
Atlanta Aquarium
Stone Mountain
Kennesaw Mountain battlefield
World of Coke
CNN tour
Atlanta Zoo
Looking online, I found some others...
Fox theatre - I've seen several shows here, but didn't realize it was a "tourist" item
Atlanta Botanical Gardens
Swan house. I've lived here 21 years and hadn't heard of this, so no idea.
Centennial olympic park - I'm not sure there's much to it, but it's on the list
Atlanta History center
High museum of art
College football hall of fame
Walking dead big zombie tour
Atlanta's southern food tour
Swan House - you'll need to look this up. I've lived here 21 years and didn't know what this is
EDIT: I was trying to look this up to see what it is and came across an Atlanta Historical homes tour.
So, this might be the gone with the wind type thing she's looking for.
Centennial Olympic Park. In my opinion, not a lot to see here, but it's listed.
Atlanta History Center
High museum of Art
College football hall of fame
Walking dead big zombie tour
Atlanta's southern food tour
Several cathedrals, but I would think they'd pale in comparison to European cathedrals. Don't know.
There's also the Shakespeare Tavern Playhouse, if you want to see how poorly (or possibly how well) we do British style.
If there's something in particular you're interested in, let me know and I'll try to find out more information for you.
