The ticket was sent one day before to us. it was easy to enter using first door; short queue. just remember to have an ID or Passport to cross check the name (as they ckeck) and be on time. It does not include the Vasari Walk, but good thing is it has Audio guide which helps to know which parts is must see and which parts can just skim through (note: official audio guide is 6 euro additional on spot). Overall, happy.
