Uffizi was incredible but we were not aware that we needed our passports in order to receive the audio guides. We learned this after checking in at the museum at our tour time. Very disappointed not to have the added information and guidance, which would have enriched the experience. The David was extraordinary.
Both sites deserve separate visits. There was insufficient time to view the works in the Uffizi and then walk to the Accademia. The audio guides were good, but I plan to book a small group tour of the Uffizi next time.
