Amici degli Uffizi
The Amici degli Uffizi card was a real treat when I first moved to Florence! For 60 euro for an individual and 100 euro for a family membership, this card allowed you to visit the Uffizi, Palazzo Pitti, San Marco, the Bargello, the Medici Chapel, and many more for an entire year.
In June of 2015, the card lost the privilege of entrance into all of the museums except the Uffizi. They had forewarned us about the change when we bought it in January. In January of 2016, they have added back, all of the Palazzo Pitti museums, including the Boboli Gardens, as well as the Uffizi.
For residents, even though the card does not have the same value as before, it is still a wonderful treat. You can enter the museums at any time, see a little or a lot, and not feel inclined to spend a whole day. You can see special exhibits, and there are also some guided tours offered to card holders during the year.
