I wasn't sure I really wanted to do this tour. I thought I wanted to simply guide myself through the 22 historic squares in Savannah. I'm so glad that we purchased tickets and did this tour. Not only was it entertaining and educational, our guide, Gertrude, was fantastic and just so funny! I highly recommend doing it.
The inside info you get from the tour helps to really understand the legends and history behind the city of Savannah.
Throughout the tour we'd stop at certain places and costumed guides would come aboard and offer more in-depth information about the stop. We particularly liked the pirate at the Old Pirate House - enough to go back and have lunch there.
Do this tour. It's a blast and a great way to get around Savannah.
