Did the north freedom tour and the guide was excellent and awesome
I bought the 5 day Go Boston Card. This enabled me to use the Hop on, Hop Off bus for 2 days. We saved a fortune purchasing this ticket on line before we arrived. Visited the Aquarium, Museum of Fine Arts, rode a Swan boat, had a tour of Fenway and many others. Decided to use the special attraction ticket to attend the Red Sox game. Excellent value and a free harbour cruise thrown in too. Would recommend this to anyone visiting Boston.
I think the Go Boston card is worth the money paid. One of the drawbacks for us in getting to do more of the activities was that we did not have our own transportation. We had to use public transit so some of the activities we would have done outside of the Boston area we had to skip.
