We took this tour with our family of 4 (including 2 sons, ages 22 and 24). Our tour guide was Antonio. All of us really enjoyed this tour and felt that Antonio was a fantastic guide. He made sure everyone in our group of 8 could safely operate the Segway, then we took off. The route was perfect...we saw a castle, the Duomo, the Teatro al Scalia, went through the Brera neighborhood, saw shopping areas, etc. We stopped at major sites and listened to Antonio's explanations of them through the earpiece listening systems. Despite there being plenty of people around these areas, crowds were never an issue with us navigating on the Segways. Antonio always made sure everyone made it safely across all intersections. Finally, having been on several Segway tours, I felt that these machines in particular were maintained very well and were very smooth and easy to operate. This was a wonderful tour, and I would highly recommend it.
