After our escorted tour of Italy which will start and end in Venice, we plan to take a train from Venice to Trento by way of Verona. We are having trouble finding a car rental in Trento that is open on Sunday, when we need to pick up a car (July 10) so that we can drive to Rumo (Marcena, Mione) as I look for relatives and family records. Because of constraints on both sides of the Atlantic Ocean, we cannot change the date for our auto rental pickup. We are coming from the USA, and I have never been in the birthplace of my mother and grandparents (Mione and Pellizzano). Does anyone know email addresses for car rentals that would let us pick up a rental car on a Sunday? Thank you.
