Took my 11 year old granddaughter to Boston just to hang out. I had found out about CityView Trolley Tours online the night before we left and purchased our tickets on line. They have 9 different stops where you can get on/off as much as you want. I'm fairly local, so am fairly familiar with Boston's sites. The stops were very convenient to many different places to see and things to do. Some of the drivers were better than others, but overall they were very positive and knowledgeable. The cost for this tour is considerably less than another trolley tour (that has many more stops) - but I was definitely more impressed with this one. I'd tried the other one before - and it's fine, but CityView's prices are so much better, I never had to wait long for the next trolley, and there were ample stops.
