My wife & I are planning a trip to Croatia in September with a proposed itinerary of Dubrovnik --> Split --> Hvar --> Rovinj (via Split) before ending our trip in Venice. While in Dubrovnik we may also do a day trip to Mostar.
We're not planning on renting a car during our trip. I've never driven outside the US and Canada, and don't feel comfortable driving in Croatia (and Bosnia-Herzegovina) since I don't drive much back home in the US (we live in a major city and don't have a car).
In our research we're struggling to find quality ground transportation options such as private car hire/transfer for getting from Dubrovnik to Split, and Split to Rovinj. The options we've found seem surprisingly expensive given our past experiences with hiring private car transfers in Europe; we used it 3x last September while traveling from Czech Republic --> Austria --> Slovakia --> Hungary during the refugee crisis and had a great experience with it.
We're a bit hesitant to take buses, especially for the Split to Rovinj leg of our trip because of the duration. Are there reputable private car transfer companies that one recommends in Croatia (from Dubrovnik and Split)?
Thank you in advance for your recommendations and feedback!
