should only book with the official sites as there are no agents from Viator to meet and greet. One office at Cafe Arnold, the second a half a kilometer away and still looking for the third office to retrieve my prebooked tickets. I did not get one guided tour that I paid for and I had to queue for each attraction visit in spite of the claims "skip the queue"
This was a new item when I signed up for it and although it read fast track and specified a date and 4:30 time slot that was not the case. We went to the line when we learned there was no fast track and they actually told us it was already closed for the day so could not enter even with the general public line. Disappointed to miss visiting this gem since it was our last day in Florence.
