Hi thank you.There is a safe in our apartment already I have nationwide cards but was wondering if cash at the bureaux would be better

If you have a nationwide card, use it. No commission and a better exchange rate than you'll get anywhere else, normally at least 5 cents better.
I used mine in April when the rate in the resorts was 1.19 and I got 1.27. Over a fortnight's spending money that's a couple of meals paid for.
And you have the added safety that you're not carrying a lot of cash.
We normally take a card each, just in case, but we've never had any problems with the ATMs.
I should add that I'm talking about a debit card, a credit card will incur a small charge in ATMs, just as you would in the UK. But not in shops/restaurants.
