I live an hour away from Boston, so I go there on occasion, i never stayed in a hotel overnight though, its a nice city and its actually pretty lbgt friendly, I wouldn't rent a car, its like 30 dollars a day to park your car in Boston, unless the hotel has parking included, the T can take you anywhere in the city for like 2 bucks each way, I suggest walking around and checking the restaurants out while your there and the park
