Good way to see some of the historical sites up close. Don't know if the 6pm tour is the best. Our 70 minute tour was cut short to 50 minutes. Tour guide said ours was his 3rd tour of the day, so we suspose he was tired.
So worth it. For our first trip to Boston, it was perfect. Our tour guide was very knowledgeable. We thought we were going to have someone dressed up in period clothing, but it didn't matter at all.
Our guide was great. Engaging, personable, and very knowledgeable. The short highlights tour was perfect for our compressed schedule. All agreed we will do the longer version in the future.
