Really worthwhile doing this tour to get your bearings and view parts of the city you probably wouldn't get around to seeing. We used the tour bus both days. If you have limited time, just sign up for the 1 hr city route, if you plan to do the tour that takes in Fisole, then have your lunch up there, otherwise, it's a waste of an hour of your day watiing for the next bus back down as there is not really anything to do or good veiwing points. We are a family with teenagers and they enjoyed taking the bus because it gave them a chance to sit down as there is soooo much walking to do in Florence.
