My wife and I are soon off the Florence for a weeks holiday. We have identified a list of places we want to visit when we're there (Duomo and associated museums and buildngs,the Uffizi,the Galilieo museum, the Accademia, the Pitti palace complex (inc Boboli gardens) and the Santa Maria Novella and Saint Croce churches).. At first glance, the Firenze card looks a good deal but when we've looked at it more closely, I doubt we'll actually save any money as we have to use it 72 hours. However, it strikes me that the real benefit could be in avoiding some of the queues. From your experience/knowledge which of these places is likely to have the longest queues (we'll be there 7th April to12th April). and how long are they likely to be?
