The whole day was fantastic, we booked the full day tour and it really was a packed day. Got to see all three Davids (two copies and the original), oodles of beautiful pieces of art and loads of information about sites within Florence. The lunch was good, though we skipped out on the desert as we wanted to use the spare few minutes to nip down to the leather shop street. It really is a lot of walking on the second half (so bring good shoes!) and it ends roughly around 6:00pm so try to avoid booking dinner to soon. Loved the whole day, would definitely recommend over and over.
