Same as BrianSue, we get the maximum allowable amount from ATMs using a Credit Union cash card (three separate cards as back-up) and then pay for everything with cash. Credit card international fees add up pretty quickly if you use them for all the little purchases as well, so we carry them for emergency use and for any on-line purchases.
The other problem with credit cards - which are CitiBank - is they seem to take great delight in cancelling or suspending cards under the silliest pretexts despite being told over and over that we travel and we buy stuff on the internet and we have regular payments as well and they really need to recognise that and get over their paranoia
