There is no real good place to park for a commuter in ATL. I have heard the same hotels that Maddog mentioned. It's a rip off and I don't know what kind of safety and insurance they have to cover your vehicle if something should happen. I heard that The Parking Spot gives a good deal to airline pilots. You might want to talk to Wally Park too. My company has an agreement with them and all I pay is 25 bucks a month. It's cheap compared to the alternatives.
