24 Hours In Boston

What all did we get up to on our pre-cruise day in Boston? With no planning (other than dinner reservations), we arrived in Boston at 8am and managed to do: - Public Gardens - Boston Common - Granary Burying Ground - Sam Adams Taproom - Quincy Market - Boston Harborwalk - Dinner at Bar Volpe All of this after waking up at 2am too! We really enjoyed Boston and would definitely visit again! What would you recommend to do on a trip to Boston?
