Definitely the worst hop-on hop-off tour that we've ever taken. Do not waste your money. They waited entirely too long at the stops and they are trying to make a section of the city interesting that just is not worth your time. There are a couple of nice views that the bus will pass, but our entire party was so bored sitting still waiting at the stops, really it was a bad choice. We've used this same vendor in at least 8 other European cities and would recommend those.
