We purchased tickets (48 hour) for this attraction online before we arrived in Florence. Had been told by our daughters who used this service in 2006 to take Line B....best tour by far they said. Had a current brochure for this attraction from the hotel, and it told us where to meet to catch the Line B bus and the schedule. Took a taxi to the designated area, got there 1/2 hour early...then waited over an hour and NO bus. Found another Hop On Hop Off location, caught a bus that eventually came along, but it was Line A, not the B we had wanted. We were told by the attendant that they no longer stopped at the designated spot we had spent an hour and a half waiting at....would be nice if they spent a few bucks and printed up new brochures w/o this spot listed as the meeting point for Line B. Said there were no more Line B tours that day, so we could catch it the next day from the same place we caught this bus. Okay...another long story....we went back to the same spot which was in front of a McDonald's and waited and waited....no Line B or Line A bus came along. We saw a Hop On, Hop Off bus leaving about two blocks down the street, and ran down to that location and knew we had missed the Line B again. When a Line A came along to that location, it was the same attendant as the day before. We complained that we had waited to catch the bus where we had picked it up the day before, and where she told us we could catch the Line B. We were then informed that they only stop in front of McDonald's if there is a shift change, which there had been the day before, we noticed they switched drivers and the driver got off and went into McDonald's. Okay, so we're S.O.L. on Line B....they run twice a day, we take the Line A bus again and see the same crappy joke of a tour that we saw the day before. You are much better off walking, we saw all of the sites just by walking around Florence that we saw from their bus. Both days, my earphone connection did not work....What a waste of time and money! They have no real schedule or meeting place. They do as they please, and don't really care if they please their customers or not. Didn't want to hop off, as we figured no bus would ever come back along to pick us up. We have done Hop On, Hop Off busses in many cities, always had good luck....not the case here or in Rome. There are many other companies that offer these services....pick any of them, but this one, none could be worse than City Sightseeing Firenze Hop On Hop Off! Another thing...they say the price of the bus includes all these attractions that they pass....these attractions are all free to the public anyway.
