Thank you kindly “Willtravel4food” for your thought. The liberty is not available for july 4th. Is the Marriott Cambridge hotel in walkable hotel distance to MIT campus. Just read that MIT wires the campus with speaker so one can see fireworks along with Boston Pop music. You mention the T station, does it mean one has to take train to the Longfellow bridge, which may be super crowded . My wife can walk about 3/4 mile or 1 if it’s not hilly. We will be doing college visits so we will need cars to go from one campus to another. Thanks
