There is so much to see and do in Croatia. Šibenik is on the Dalmatian coast. While you’re not likely to find the canine variety here, you will find the human variety in spades.
If you’re interested in reading more about Croatian and American cultural differences, I recommend Chasing a Croatian Girl by Cody McClain Brown. You will learn all about how Croatians believe wind can kill you, the sea can cure any ailment, and how sitting on the cold ground will make you infertile. Bringing cash to Croatia is a good idea to pay for small things like drinks, snacks and souvenirs. If you go to your bank ahead of time, you can order Croatian Kuna, Euros or both. Euros are accepted throughout most of Europe but not in Croatia; Kunas are the only currency used in Croatia. If you plan to travel outside of Croatia, I recommend getting both for your trip. If you have a credit or debit card with no foreign transaction fee, plan to use it for the bigger expenses such as hotels and car rentals.
