Agree! CFB HOF is so much fun for all ages. Piedmont Park is also fun and has a great farmers market Saturday mornings. There’s a great Cuban food truck, and I also highly recommend Emerald Bagels (some of my favorite ever, and I lived in NYC for a few years). My son also loves the Fernbank (science) Museum, but that’s a little farther out, so you’d need to drive or Uber out. Worth it though. Midtown also has great art museums (High Museum, Center of Puppetry, MODA), if you’re into that.
I also agree 100% on everyone’s hotel recs. Also there are no good restaurants or anything else to do in downtown. But I think some of y’all might be confusing downtown with Midtown? Downtown Atlanta is the area further south, near where the government buildings are. Midtown is nicer and where GT is. We don’t refer to the whole “city” area as downtown here.
Edit: oops, I think I may have replied to you when I meant to quote you - sorry dude!
