First off the lady in the ticket booth was very rude and condescending. We were told that the trolley was leaving at 2:36. When the trolley arrived, it was full of people and we had to wait about 25 minutes for the next trolley. The tour itself was great, very informative and interesting. The driver was very nice and knowledgeable. When we arrived at Mallory Square, we were informed that if we wanted to continue the tour and return to our original stop, there was another trolley that would be leaving in 25 minutes. The trolley should have continued and changed drivers if necessary but not just leave us stranded with nothing to do. I recommend the tour but be advised it may take longer than the hour and 20 minutes they tell you it takes.
