Subject: Re: Viking Grand European Tour
Most places in western Europe I've gone to in the last year or so take payment with my iphone (Apple Pay) which makes things even easier since I don't have to take a credit card out at all. I just make sure it defaults to one of my no-foreign fee credit cards although you could load Apple pay with cash and pay that way.
Not sure if this is obvious, it wasn't for me, but in Apple's wallet whatever card is at the bottom of the display is the default payment. You can change it by simply dragging a new card to the bottom.
In my case I have a debit card, several credit cards and Apple cash listed.
