We will be in Florence in mid-October for only 2 days. We will arrive early in the morning via train from CT. At that time of year, is it possible to buy tickets from the ticket office for later in the day (or the next day) without waiting long? Or should I just commit to a time and buy them online. (Having to create an account on the website is also annoying and a deterrence, but I'll do it if I need to.) What happens if, by chance, we miss our time? Are our tickets void?
Thanks in advance!
