AA 1359 - ORD to ATL - plane was about 1/2 full......no meal service, only drinks and small snack bags. AA terminal in ATL is awful and it is hard to get to rental car buses.
Hertz - sucks again, no upgrade of car.
Grand Hyatt Buckhead- hard to find entrance to hotel, but service is excellent and rooms are nice. 9 rating so far!
