|It's always a good idea to phone up your card provider (and bank) to say when and where you're going on holiday.
This is not to defeat possible fraud rather to stop your card being blocked. Anti-fraud measures often mean a card that's used today in Manchester and tomorrow in Greece has a block put on it.
I have had my card blocked once for just this reason. When I called my Bank the problem was sorted out within a few hours but still, I didn't need the aggravation.
