If you only have a day in Boston, this is the only way to do it! We covered all the major places in the city that most travelers would want to see. We had planned to walk the Freedom Trail separately but as it turns out, you can get off and on and still stay with the red brick trail! 9 stops and we had a different driver each time--all were personable, entertaining, and had interesting stories to tell. Don't forget to give a gratuity to each one! The only negative was that some of the stops and pick up points were not well marked, due to various construction going on. 2 thumbs up!
