As I am planning out our big Italy trip, I am getting to the tail end of it (we have 5 weeks) and was considering hiring a car in Venice and heading northwards through the Dolomites and eventually back down, dropping it off in Verona. My current schedule allows 3 days for that, which may be a bit much. (I had originally planned to just take the train from Venice to Verona and then perhaps daytrip to Trento or somewhere on Lago di Garda).
Has anyone done this drive or something like it? How much time would it realistically take? I'm keen to be using the car to see the scenery, but not sitting in the car all day.
