Forget the travellers checks.

I was in Spain in early May. I found the Spanish continue to be more cashed based than credit based than the US. Many many restuarants, shops and hostals want cash and not the ole Visa card.

I found ATMs on almost every corner in Madrid, Seville, Cadiz, Estapona and Granada. I'd called my bank ahead of time and told them to expect ATM usage from me from Spain. I had no trouble getting Euros and the exchange rate I got was excellent. I travelled with a couple of days of cash and reloaded at the local ATM...about like I do in the US.
