Yes, many people don`t like "Ibiza-like" mass/commercial tourism, but want a peace and natural beauty for their family-vacation. There`re still nice and quiet places...yes, Dubrovnik and Cavtat near it ... islands... but, the world is changing...
Well, not that close - Dubrovnik is on the south, and Zadar in the "middle" of the Adriatic coast... Huh, Dubrovnik (and the whole area) is one of these "perfect", beautiful and "sacred" places... Last time I was there four years ago... One photo from the Zadar, also very old and nice place...
