Closer to day-trip to ORD/LGA when I have the munchies unless I'm really missing something about what ATL has to offer?
DL flies 7x daily from CLE and 4X daily from CAK
WN flies 3x daily from CAK
F9 flies 5x weekly from CLE
You won't know unless you try.
For the GT and Chinese hot dog at Chai Peeking alone it's worth it.
Attractions... Never been to any. You have Coca Cola, aquarium, CNN center.
Added bonus is experiencing ATL. Truly a massive airport. And the DL lounge has the fancy Coca Cola machine. You can play to your hearts content.
