Hello, I am flying to Sarajevo this summer with my 3 kids (ages 8, 10, 12). We will go to Mostar after a few days in Sarajevo and then from here I am a bit torn. We will be making our way up to Slovenia.. My question is:

a) Do we hire a taxi to take us from Mostar to Una National Park to stop for a few days before we go up to Ljubjlana also by taxi? This looks to be quite expensive...

or

b) Do we take public transport from Mostar to Split and rent a car in Split (maybe stop in Zadar or Livno?) and drive up to Ljubjlana?
