I agree to this.

However, imho it's not the main reason people take out cash for holidays. Imho people don't know what to expect in the new location. I've been this year at a wonderful location in Greece that had no ATM (OK, next town, a few miles away, had that). And almost everybody still prefers to be paid in cash. So having cash on you to cover for the holiday is a pretty much expected approach, no matter what politicians and banksters tell on TV.
