Suggestions needed for how to purchase train tickets/car rentals. We'll be leaving Roma and headed to Venice, then needing a rental car for 4 days from near or around Venice (we're headed up to the Dolomites for a few and want to tour by car). Then, car rental return in Venice, 4 nights stay in Venice, then train from Venice to Rome.
We want to ride 1st class and I've looked at Trenitalia-can I advance purchase these tickets and save some $? Is there another train I could take? Also, any recommendations for the car rental? We are not looking for anything fancy in the car, but we'd like unlimited mileage.
Thanks in advance!
