I go to Atlanta quite a bit due to work and have had the family there for tournaments too. Entertainment wise- the Georgia Aquarium is cool, skip the World of Coca Cola next door. You want educational - go to the National Center for Civil and Human Rights. If your son is high academic and D3 ish do yourself a favor and visit Emory. If I could do it all over again I would go to Emory but to be clear they wouldn't have taken me (grades).... Eating wise there are too many choices in ATL to give advice. You might also catch Hawks vs Nets / Milwaukee (go Nets) if they close out Sixers, don't sleep on that possibility. I once got to tour the Hawks practice facility, its amazing but not sure you can buy a tour there. I am not a soccer guy but the Atlanta United are a huge draw in that town too. Have fun and good luck.
