Firenze card

You must make reservations for the Uffizi and Accademia if using the card. Those can be made before purchasing the card and before arriving in Florence. Reservations for climbing the duomo's dome are also mandatory but cannot be made until you are in Florence.

See the FAQs of the Firenzecard website for details, specifically the "Do I need to make reservations for the Uffizi and Accademia Gallery with Firenzecard?" and "How can I book the Cupola climb with Firenzecard?" sections.
