This hop on hop off was completely a waste of time. In Florence, you are better off just walking around. We got on the bus and at our stop, the bus "stopped" for 5 seconds...not enough time to get off. Don't do the Florence City Hop.
Very excellent hop on experience. Takes you everywhere you want to go. No problem finding the stops and they even waited at the Vatican for 20 minutes for people who just wanted to take pictures and get back on.
Loved this hop experience. Lots to see and plenty of opportunities to get on and off. Easy to find from the pier and on all of the stops. The drivers were very friendly and helpful.!
