Two adults, two teenagers and we had a great time. We did this for the Segways more than for the history and we would have enjoyed more time playing around on them - they are as fun as they look. Joseph, our guide, was very entertaining and we learned about the distillery district and some Canadian history. The half hour tour was the right amount of time for us. Also, we likely wouldn't have visited this neighborhood and it seemed like a fun area to walk around if we had more time.
