Quick question: are Euros used in Croatia or is the local currency still in use? Thanks!

As far as I know Croatia is not even a member of EU.
Its money is kuna

Kuna is the official currency, but we didn't have any problem using the Euro last year on our visit. If you're thinking of making a trip to Montenegro, their official currency is the Euro, although they are not a member (yet) of the EU. ENJOY!

Just there in Sep. You can use Euros EXCEPT to pay for the walk around wall. They wanted Kuna only. There is an ATM just outside the entrance to the old city on the right hand side. We just got about 300 Kuna and it lasted us for everything we needed.

I was just curious as all of the hotels have quoted their prices in Euros and the private guide we have hired quoted in Euros as well!

Thanks!

This is similar to the question of whether you should have foreign charges posted to your credit card in the local currency or in $US. Paying in Euro rather than Kuna allows the vendor to establish the exhange rate and it may or not be the same as the official rate. To guarantee the best exchange you should use an ATM (there are lots of them) to get Kuna. As an alternative you could get them to quote the price in both Euro and Kuna and determine if you would be getting a good exchange rate.

we will be arriving at the Dubrovnik airport and wonder if we can use Euros to pay for our bus trip to the main bus station?
