My husband and I have booked a small group tour of Venice, Florence and Rome for October 2026, but we're wondering why Tauck will be giving us "privately guided" tours of the Uffizi Gallery and Vatican instead of the "after hours" tours that are offered on other Italy excursions. To us, this implies we'll be joining the throngs with a guide, but won't have any kind of exclusive after hours access. Can anybody comment on their experience with this? Many thanks!
