This was an open top double decker bus with a front cowling. It was a fairly cold day and we were glad that we had hats. The tour bus scheme gives a ticket valid for 24 hours, during which time you can hop on and off as many times as you like. But I doubt that anyone would do that more than once or, at the most, twice. I mean, the places we visited lasted about two or three hours each time, and going from A to B on the bus is dog slow, although you are getting the sightseeing in. It was expensive, but it did include one river trip in the price, which was worth doing.
