Hi Nipper,
We take our debit card as an emergency back up, but use a Post Office credit card (serviced by Bank of Ireland) as it is commission free. We have also in the past preloaded the card, so in the event of having to with draw cash at an ATM no interest is charged.
Remember to notify your bank and credit card supplier that you are going in case they block the card due to unusual usage.
For ATM withdrawals and general debit card spending I use a Preloaded card from My travel cash.

The card is free, earns cashback, and can be used in most places. You will only be charged if it lies idle for a year.
The other advantage is that you can reload it by phone whilst abroad or when at home watch the currency exchange rates and load when they are good. It also restricts your losses if stolen although if you report it, the card issuer will cancel it and issue a fresh one with no loss of load.
Remember to always pay in the local currency if offered a choice of euro or sterling by the trader as you may be charged at an extortionate rate if you choose sterling !!
Most of this info is readily available on

Not sure how it all works if you are based in the south and your cards are euro based.
