My family (2 pre-teens) and I are traveling to Croatia for the first time next summer. I'm researching where the 'not to miss' places are. We will be coming from Venice to possibly Bari- and taking a ferry over. Would like to see Dubrovnic but not sure other than that. I would prefer to have one or two home bases that we can explore from, instead of moving around every couple of days. With this in mind- would we need a car or is public transportation available? We would love beach time, seeing historic sites, active things (possibly scuba diving). It will be in July and we have two weeks. Any advice would be greatly appreciated!
