re: Heading to ATL...need advice!!!

I always park at the Marta station either on the west side or north side near perimeter.

You get in and out quick, and despite it's reputation the Marta trains are fine. They will just be packed with fellow football fans.

Hotels on the west side past six flags can be had for cheap. Just look at interstate 20 and Georgia highway 6. I have stayed at the Fairfield and spring hill suites in lithia springs. They are both clean with restaurants nearby and easy access to interstate 20
