Keep your Breeze card; you'll need it with you as long as you ride the system. If you're going downtown OR riding after 7 p.m. it doesn't matter which train you ride, otherwise it does.
Going to the airport? Park at Sandy Springs for five bucks a day! It's 42 minutes to the airport, which is as fast as or faster than driving in the morning and evening traffic!
MARTA is perfectly safe and as clean as a subway system gets. Support public transportation and save a ton of money by riding MARTA to your Atlanta destination!
Visitors may not be aware that thanks to several layers of completely incompetent local governments, MARTA only goes to places you certainly don't want or need to get to, except downtown.
You might have to wait for the train to leave, but any wait is better than driving in Atlanta (if my hair was long enough to grab hold of I'd've pulled it out in Wed's 5pm traffic).
Marta is ok if your not a frequent rider. If your a reg. pay online, CC machine down all the time.. Employees are rude as they deal with negativity all day. Make sure your early or your not on time!
If you lost your ticket or card you can still get pass the gate. Simply wait for the gates to close and then walk up really close to it (almost kissing it) and it will open. :-\
