Great experience! Our guide, John Hancock (aka Timothy) was terrific. Brought the experience to life and told interesting stories throughout. Family of 5 -- three kids (20, 18 and 14) enjoyed every minute. Only complaint -- the group was rather large, more than 50 probably. But then again, it was the 4th of July. Easy to understand why it was so crowded. Recommend this to everyone visiting Boston. Our guide gave great tips for eating and further touring (on our own) after the guided tour as well. Thank you!
