请问有人用过FIRENZE CARD吗？

网站上的介绍看上去很诱人啊，不知道实际使用的便利性如何：


The Firenze Card is a 72 hour card that gives you free admission to 33 of the most important museums in Florence. You will have access not only to permanent collections, but also to exhibitions and all other activities held in that museum without further cost. You just show your card at the entrance to the museum . The card can be used once only in each museum, and it will provide free access to all EU citizens under 18 who are accompanying you. To use your card on public transport, just swipe it against the validation machines located in every bus or tram.
