My wife and I are traveling to Cental Europe next Sept. We have allocated anywhere from 7-10 days potentially for Croatia. Our last stop before Crotia will probably be Ljubljana. At the end of our Croation trip we are planning to ferry across to Venice from Rovinj. Our initial thoughts are to get to Dubrovnik (somehow) and make that our base to day trip to the islands, Split, and to just relax in Dubrovnik. Should we get a car while in Dubrovnik to do this? And, should we be considering any stops above Split but before Rovinj?
