I really enjoyed your trip report. I go to Spain a lot, but mostly go to the north shore (cousins in the northern province of Asturias). It was nice reading about the south of Spain, since it's been years since I have been there.
That was an excellent trip report! My DH and I are going on a very similar Spain trip this March (also includes two days in Portugal). Having never been there, how did you handle finances, thru a debit card? I'm the type of person that likes to have separate envelopes of "cash", actually travelers checks, for each day of our trips. I'd love to do that with Euros, but not sure if that's the best way to budget in Europe. Any info would be a tremendous help!
Although the exchange rate might be better when changing money there, my opinion is that it is still a good idea to take a healthy amount with you, not just one day, to use.
I agree with letting your banks know ahead of time that you are going to take your cards out of the country, so they won't cancel them, or put a hold on the money (that happened to a cousin of mine, and she spent a lot of time on an international call to straighten it out).
Here's what happened to me in 2011. I was staying in Madrid, and had made a day trip to Segovia (love that city). I put my debit card in the ATM to draw money. Realized that I should have taken out more, and put it in again. The ATM ate it. I called the bank listed on the ATM. They were already closed, and would be open the next day, but I was told that the card would be canceled, and I couldn't get it anyway. I called my home bank, and they told me the same thing. That they themselves would cancel the card, and I had no recourse. Luckily for me, I had another debit card (my main one), and used that the rest of the trip. I was super cautious by then, though, and only used it to purchase things. I waited until I was with family before using the card in the ATM machine.
Also, I agree with everyone who said to use a card that won't ding you for international transactions. My American cousin who had gone with me ended up spending a lot of money because she drew money out of the ATMs a lot and had to pay an international transaction fee every time she used the card, whether it was for a purchase or to draw out money. If you do have a card that is going to charge you, then it's prudent to deal primarily in cash, and use the cards sparingly.
