Hello. I will be visiting Florence in a couple of weeks and have a question regarding the OPA Pass. We plan to visit the Duomo & Crypt, Baptistery, and Palazzo Vecchio & Tower. Entry to the Duomo is free. The Palazzo Vecchio has it's own fee associated with it. But I can't find a fee from the Baptistery and Crypt separate from the OPA Pass. Is the only way to gain access to the Bapistery is to buy an OPA Pass?
