How is the Avis station at ATL? The only recent experience I could find was
this one which indicates it's abysmal, but the OP of that thread only has one post at FT, so maybe not reliable. (That thread was in the general car rental forum, hence I started this new thread in the Avis forum rather than respond to that.)
I have a reservation there and another with a competitor at ATL in two weeks, but both stations seem pretty bad from what I can gather here at FT...
