How far in advance should I purchase tickets to the Uffizi Gallery and Galleria dell' Accademia in Florence?
I was just in Florence and the entrance lines...even at 5:30 p.m. were very very long. If you google "how to buy advanced tickets to the Uffizi" you should get good info. I would book ahead if you wanted to go.
Depending on how long you will be in Florence, the Firenze Card might be useful in avoiding lines and seeing other amazing sights.
