We choose to do this because we love history and wanted a good overview of Atlanta. Don was a great tour guide, even playing the harmonica along the way (songs related to Atlanta). He was very knowledgeable, well spoken and has a nice loud voice when necessary. Corey, the bus driver, took care of us and was friendly with those on the tour. You stop half way at the CNN center to eat in the food court. There are plenty of options. Our favorite part was the MLK Jr. centers and church, and the beautiful mansions in Buck head. Allow plenty of time, the whole thing takes 5 hours.
