I just had to post to say that we were so pleasantly surprised with our week long stay in Atlanta. Everyone we met throughout the city was extremely kind. Hotel staff, restaurant staff, cab drivers, even the security at the airport was kind! We left with such a positive impression of the city as a result.
We did not rent a car and found the Marta rail to be extremely clean, safe, and convenient. We even had the driver wait for us as we were running through the station with luggage when we were leaving to catch return flight!
I highly recommend a visit to Atlanta and I hope that all you trip planners experience the same hospitality that we did. What an awesome city. Well done, Atlanta.
