I am flying into Venice this June for about 3 days, then I want to explore Tuscany (maybe Sienna and Florence) for about 3 more before heading to Salzburg, with final destination in Zurich. I am assuming the drop-off fees from Italy to Zurich would be huge, but I much prefer having a car than train. We love to explore the non-tourist towns. Any suggestions about how to get to all these places (12 days total) the most economically? I have thought about renting the car and dropping it off as close to the border as possible near Salzburg, then taking a bus or train just into the city. While is Tuscany, we would like a farm-stay if you have any suggestions or rent a room with a local.
