I drove from Conyers (outside of Atlanta) a few times, and from Marietta. I also drove from the DC area once. I alsawys compare the time - driving or getting dropped off at the airport, checking in 2 hours ahead of time for security, the length of the flight, the possibility of delays in ATL, the wait for the luggage in MCO, the rental car wait. If the time is near equal, I will drive, even though I just park the car and leave it for the time I am there. I wouldn't do it from here (1 hr north of Boston) unless I was able to stop once or more each way. And that takes up way too much of my time in the world. It's also only me ever going, that's why it's way too long to drive now.
