We had a great experience on Grey Line's "all loops tour" in NYC. You can hop on and off the bus at any time, and can do upper Manhattan Loop, Lower Manhattan Loop, Brooklyn Loop, and the Night Time Tour for one price of $54. The ticket is good for 48 hours. We enjoyed hopping on at Times Square, hopping off at Central Park, then to Harlem, down to the former World Trade Centers, and night at the Empire State Building. Really a great value, educated tour, and lots of options! If you haven't been to NYC and done an organized tour, it's worth it.
