Booking gets you in during the busy season. Sometimes you can arrive and do not need to use the reservations line so forget to mention the booking and save 3 Euros per person. Avoid June and try the winter period for a calmer visit.
They speak English and are helpful.
Instead of queueing for two hours to get in the Uffizi or one hour for the Accademia or Pitti Palace, call the hotline to book tickets for a three euro surcharge per person. They'll give you a booking number and you pay at the museum's ticket office. Number valid for all state musuems, hence the above plus San Marco, Bargello Archaeological Museum etc.
