Cambio at the airport

Capital one charges no foreign transaction fee and rebates local ATM charges (max of 4 a month as I recall) I believe Schwab has a similar card.
Your situation is very convenient.Wish I had access to such choices. Given the current exchange rates, when we returned from Europe this spring I did bring a supply of € and £ for our next trip. Admittedly in Europe you can almost do without cash. Almost everywhere has touchless pay available, including many but not all public restrooms.
