Arthur, our tour guide, was very knowledgeable of Savannah. Tour covers very interesting spots in Savannah. The jump on - jump off option is nice, although we did not do it. You should be aware that you get a different guide with each Trolley, so if you do jump on and jump off, you will probably have a new guide. Sometimes Trolleys are full at very popular sites and you have to wait for another Trolley, although they appear to be only 15 minutes apart.
