I'll be going to Atlanta to see a couple of games during the Mets series.  I haven't booked my hotel yet.  Any suggestions?  Some things that I'm looking for are:

a.  Cheap and walking distance to the stadium  

Or

b.  Cheap and not too bad a drive

Do you know of any places that offer shuttles to the games?  Or a nice place that is close to public transportation?   I don't care too much about frills.  As long as the place isn't a complete dump, I'm not too picky.  I would appreciate any suggestions.
