The luxury motor-coach will depart from town hall at 8 am and will drop you off in the heart of Boston at Faneuil Hall. You'll have about 8 hours to sightsee, shop and eat. Then the bus will pick you up for the return trip at 6 pm. For only $35 per person.
Walk the Boston Common, take a Duck Tour, eat lunch at one of my favorite Boston restaurants. Lots of ideas here.
