Anyone not buy the combo duomo ticket to climb in advance. Not sure if my train will run late when I come in on a SAT so I don't want to book a 1630 climb time if im not sure. Anyone waited till day of and just paid to climb the dome that day?
Please reference the Duomo website:
https://www.museumflorence.com
Tickets are only available for the entire complex, and pre-reservations are mandatory to climb the dome. You can make that when you order your tickets. Slots for the dome fill quickly and in advance: according to the site, as of today the next opening is on 4/26.

Your tickets are good for 72 hours from first validation so if you think you can't make a time for the dome on arrival day, book it for a different day you'll be in Florence.
Editing to add, I just heard from someone I'd assisted on another forum that they made the mistake of choosing not to buy tickets until their Wed. arrival day, and all the time slots for the dome were already filled through the following Tuesday. And it's only shoulder season!
