We will be flying into Milan later this month. We will be spending two weeks visiting Orta San Giulio, Mantova, Ferrara and other places in the area. We are renting a car at the airport. On toll roads with electronic toll payment is there always a toll booth so we can pay cash? There is an old post on Tripadvisor where a tourist, in the Milan area, was not able to pay and was billed months later with horrible fees attached. I would appreciate any info. Thanking you in advance.
