I was just there, and coincidentally, I was born in Korcula, and even more coincidentally I have done some work for the ministry of tourism, so if you guys have questions, shoot, and IŽll answer whatever is in my capacity. True, the roads are shitty and not designed to take the ever growing number of tourists each year, but island hopping on farries is something you might want to consider. For unesco protected areas like Kornati Island, and especially Dubrovnik, book early, like right now. Have fun!
