We will be flying into an out of Marco Polo Airport (late June to early July) and after staying in Venice will want to rent a car to drive up to the Dolomites where we have rented an apartment for a week. We will want to return the car either at Marco Polo airport or close to it for an early morning flight out when we leave. We have reservations at Hotel Antony for the night before we leave. What car rental agency would be recommended? I know Dollar, Thrifty Budget and Europcar are available out of Marco Polo. Also we are concerned about how much and what type of car insurance we should be buying while driving in Italy. Thank you for your advice.
