Thanks for the info.

Didn't think about returning the car for a few days in Venice, then picking it back up when we are ready to leave. Have to check what that does for the rates.

Yes, would pick up and drop off in Italy, just visit Switzerland but it looks like we would have to take a train in. That is an idea which I may look into. Do the train stations typically have parking where you can leave a car for a few days? Would think we would depart somewhere like Milano, or east/west of there and not Venice, Rome, etc.
