Take some time and plan your activities. we saved some money, and saw some great things that we would not have considered if it wasn't on the card. Do not hop on and off the shuttle (there may not be room to get back on) instead stay on and do the full circuit and take the subway to the individual attractions. Make sure you know how to get to Macys to pck up your card, and to the main beantown trolley desk to get your trolley tickes.
Tour had much to offer and discounts on the local attractions.
