Hi, I'm traveling around Europe right now and heading to Naples, Positano and Rome next. I'm mostly in big cities (like London and Barcelona) and I found that I really don't ever use cash. I put everything on the credit/debit card. (I have cards with no foreign transaction fees).
I'm not worried about big cities like Rome, but I am concerned about Positano. Is there any reason I should make sure to have some Euros on me? I'll be heading to Positano in a week.
I would love to get the updated recommendations on the cash issue. I've seen some old posts, but it seems like more and more places now accept cards.
