New York City, New York
Good for orienting yourself in NY, but subway is better and cheaper if you take a little time to understand system. Some tour guides on bus good, but some very ordinary, especially one who would declare every 2-3 minutes "I just love New York, but it is sooooooooo EXPENSIVE". Also remember to duck your heads for low branches. And take something waterproof, if it rains you and the seats will get wet.
