I'm attending a summer school in Cortona for two weeks this summer. Major expenses are paid already.
My question is if it's possible to pay all the dinning and grocery with credit card or debit card issued by US banks (Mastercard or Visa) in Cortona? Or I still have to use cash?
In the latter situation, I've seen an article claiming that it's wiser to bring US dollars and then change them to euros when needed. But it's usually about traveling to big cities like Rome or Florence so I wonder if it's easy to do that in Cortona?
