My husband and I are planning to do Salzburg area (3 nights) followed by 4 nights between Slovenia and Croatia (and then to Budapest for 2 nights before flight home). After researching I realize that train travel in this area either doesn't exist or isn't efficient and we might be spending too much time traveling.
We are active people and want to do the Alps and lakes, but also love a glass of wine in the city at the end of the day. We don't necessarily want to spend the entire time driving but understand it's important and necessary for the area. And the more research I do on Slovenia lends me to believe that going to Istria would be a lot of work for much of the same feel. But, I have no idea.
Any advice on the best way to maneuver around and/or time split up between areas is welcome. Also wondering if Slovenia and Istria will be similar enough to leave one out (and what the preference is?)
