I would say if your kids love legos and you take them to tour/taste at the world of Coca-Cola, Andretti karting, zoo Atlanta, stone mountain park, SHOOT the hooch, chattahooche matte center and so much more. Let me know if you need anymore help with travel.
Erica, I believe Nashville is 4 or 5 hours so I would say if your expectation is that or say Disney or something like that, then no. However, it has a 4D movie that you watch (about 15 min or so), different building stations, a laser gun ride, playground(s), race tracks where kids can race cars they built and they have a pretty large lego city you walk thru. Probably close to a full day if you wanted to. Hope that helps.
It's worth it
You will enjoy, it has a variety of play areas to keep your children busy.
I drove from VA to Atlanta specifically for Legoland. To me it beat buying flights to FL or CA. I saved a ton of money.
I would say that the kids will love it but I wouldn't drive from Nashville to Atlanta.. It's not worth it, in my opinion!!
