Great guide on first trolley, very witty, funny and knowledgeable. Next trolley bus guide was so loud we got off a stop earlier than planned! Had to take a metro ride from Back Bay downtown to Macy's to get voucher and booklet for Boston go option, because Copley square mall could not/would not issue it - seemed unaware of it. Then had to walk another 15 minutes to aquarium area to get tickets! This reduced our visiting time by almost 2 hours. Used the card to visit Constitution ship but Hard Rock Cafe would not give discount and we forgot to ask in Cheers! Probably good value if you've time to visit all the museums/places offered.
really good driver commentary on hoponhopoff tours
Didn’t have time to use GO card and see comments above
