We are planning to travel to fairly rural Croatia for 2 weeks staying in Plitvice lakes then Pula. We had to pay for the accommodation in Pula with Euros and as such was wondering weather it would be worth primarily bringing Euros in Croatia instead of Kuna. Online research seemed to suggest that we are better with Kuna and some people seemed to be seemed to be saying it would be best to bring sterling and change it to Kuna when we arrive, we land into Rijeka airport and it appears that the facilities there are limited - as we are getting a coach transfer we wont get chance to visit the city after the flight.
How frequently is the Euro accepted and what sort of rate would I generally expect to achieve? And how frequently are debit/credit cards accepted?
