Each day we had a morning session and an afternoon session. The sessions were somewhat like university lecture and discussion classes, where the tutors would explain the significance of the certain artwork, architectural design, or historical context we were studying that particular day.
We normally had quite a long lunch break, as well as leisure time before dinners. The evenings were mostly for us to explore whatever city we were in, and the tutors were very lax about how we spent our free time. We were all adults, and we were treated as such, with trust in our conduct and our capability to navigate ourselves without constant supervision.
We did have some days where we took trips outside of the host city (such as Pisa, Pompeii, Padua, and the islands of Burano and Murano outside of Venice). We also sometimes had free mornings or afternoons, where no sessions were planned and we were given the opportunity to take care of any personal business. Other than those occasional abnormalities, the itinerary was basically routine.
