The driver/guide can make all the difference! One of our drivers - "Just Joe" was really outstanding, fun, and engaging! We had a total of three drivers, and all of them were knowledgeable, but personality can really take the ride from good to fantastic. All in all, good way to get around the city, although the circuits can take quite a bit longer than advertised if traffic is heavy.
How did you find such knowledgeable and personable guides? They made they day for us. AND..they are great ambassadors in our capital city.
We took the two day hoho pkg in Washington dc. The first day was not too god since the driver's voice was a little difficult to understand but the biggest problem was the poor speaker system. The other buses the rest of the time had good speakers and the drivers were easily understood. Some of the other hoho tours include a river boat ride. This one did not. All in all, I would still recommend it.
