This was a terrific way to show our out-of-town friends our hometown without the hassle of driving and parking at each site. We also returned once again as a couple to enjoy the scenery and to get a better idea of how to navigate in the city with the new bridge closings. Friendly staff, responsive to customer inquiries. It's important to plan ahead for occasional wait-times, perhaps bringing along a copy of a Boston guidebook to provide additional info for the sites near the bus stops or a storybook to share if children are in your party. Be sure to ask if route will be altered during your tour day based upon special events happening in Boston (game days at Fenway, the Garden, festivals on the Rose Kennedy Greenway, etc.) Also, we found that most of the drivers responded well when they got some feedback from the riders. Lots of fun and photo-op moments.
