We got the money at the airport from the ATM, but just in case, we bought some Kuna from the Post Office before we left, just a small amount for taxis etc. Otherwise use your debit card.
Check your credit card - the zero % rates often don't apply to cash withdrawals, and you'll certainly be paying a transaction fee and commission (unless you have an amazing card). Taking cash on a credit card in a foreign country can be very expensive.
