My wife is going to Boston @the Godfrey Hotel in the theatre district within walking distance of the Freedom Trail, Boston Common, Public Garden, and Downtown Crossing. Any advice on what not to miss and what to avoid (questionable areas after dark?). She is going with her sister and two nieces. Very willing to take mass transit and walk. Any suggestions welcomed. Going October 14-18(return early am). She likes lobster (If in town those days you may want to stay home or go on a trip!!).
