What is nice about this is the flexibility of the tickets. We bought tickets intending to do an early morning tour before an afternoon sailing of a cruise. We landed in Boston ahead of schedule & were able to join the 3pm tour at Boston Common that had just begun. We went to all the expected places on the south end: burial ground, site of Boston Massacre, oldest school, etc. It began, as I said, at the Boston Common & ended within sight of Faneuil Hall. Our guide was interesting & entertaining. It lasted just under the stated 90 mins. I think it was well worth the fee.
