I will be traveling to Croatia in the middle of June flying into Dubrovnik 4 nights - Korcula 2 nights - Havar 2 nights - Brac 1 night - Split 3 nights - Plitvice lakes 1 night - Rovinj 3 nights (flying out of Pula to London). That is what I have outlined for a basic itinerary. I'm choosing to spend 4 nights in Dubrovnik as I want to take a day trip to Mostar, the first day will be recovering from the 18hr of travel and figure it can be spent exploring some and relaxing. But I'm wondering if 3 nights is too many for Split if I spend time on the islands before I get to split. My idea was to wait and get a car rental in Split, but I read that some of the islands you might want or need a car. Any advice here is much appreciated.
The second part of this question is things to do with my Son, the one and only thing on his list is renting a bike, he would like to do some mountain biking ( Mom is a novice). Is there a good place either on my list or maybe somewhere else to consider for biking? I figure seeing some caves, kayaking, and beach time could all be factored in. This will be my Son's first trip overseas and so I really want him to experience the culture, but without boring him too much. All ideas welcome!
Lastly, if you have other suggestions on places to go instead of what I'm thinking I'm all open to ideas. Thanks!
