If I buy the combination tickets on the Uffizi website for Thursday
will that allow me to see the Pitti and Boboli Gardens on another day?
Or do I have to buy seperate tickets? I found the ticket website a
little confusing.
Sharon, there is a combo pass for the Uffizi, Pitti and Boboli that's good for 3 consecutive days. See this page:
https://www.uffizi.it/en/pages/combined-ticket
You will have to make a timed-entry reservation for the Uffizi but can visit the Pitti/Boboli afterwards without a reservation within the 3-day life of the ticket. So, if you buy that ticket and make your reservation for the Uffizi for Thursday, you can visit the Pitti/Boboli on Friday or Saturday. What you could NOT do is visit the Uffizi on Thursday and the Pitti/Boboli on any day after Saturday.
"Free" days throw a bit of a complication to the plan but your dates don't fall on any of those.
