We are planning a trip to Dubrovnik and Venice and needed transportation, either bus, train, car, etc. We thought of stopping a couple times to break up the trip... Say Zadar and later Rovinj. We have 12 days to complete the entire trip excluding flights from SFO. Any recommendations?
If you haven't done so already, I'd post your question on the Trip Advisor forum for Croatia. We got some great advice from local experts on that site.
I'm a fan of the website Rome2Rio (http://www.rome2rio.com/) to get ideas about transportation options. We are making a similar trip up the coast of Croatia and are renting a car for that part of the trip. Our plan is to pick up the car in Split and drop off in Zagreb.
