I recently found out how lucky I am to have a son who is a pilot. Free travel, anytime, anywhere as long as it is stand by. I would often travel solo. I do not wish to have to rent a car. I love hop on , hop off tours. Did the one I Boston, and Toronto,but not as a solo traveler. Looking for recommendations, of safe, interesting, destinations. Somewhere that I can easily get a transport from airport to good hotel, and from there either walk the area or do the bus thing.
