We plan to spend two night in Orvieto and 6 in Perugia (using it as a base to visit cities like Assisi, Spoleto, Gubbio and perhaps Todi, Trevi or other interesting places.
We plan on taking the train. I have traveling a lot in Italy in the past, but not in a dozen years.
Will there be a teller at the train station for us to purchase tickets? If not, will the machine teller accept American credit cards without the chip and pin?
Some of the places are not far from Perugia, like Assisi, would we do well just hiring a taxi to take us there from Perugia, if so what would be the approximate cost? (taxi would not wait for us)
Should I plan on purchasing rail tickets in advance (Rome to Orvieto, then Perugia to Rome Airport)?
Further, I usually purchase some Euros using an ATM when I arrive in the country. How much will I need for two weeks? What can't I buy with a credit card?
