My husband and I plan to spend a week in Croatia with our 13yo son in late June. We will be spending a day in Zurich on the way in and an overnight in Vienna on the way out, so I don't want to cram in too many places while we're in Croatia. I'm leaning toward staying in Split and day tripping from there to a few islands, Krka, Plitvice, Trogir, maybe a canyoning, kayaking or rafting excursion. We are from Florida so we don't really care about the beach. I'm wondering:
1) Is it a crime to miss Dubrovnik? I loathe the thought of being packed in with a bunch of cruise ship passengers, which makes me think it might be better to skip it, but we could work in an overnight or day excursion if it's truly unmissable. I think we'd like walking the walls, I'm just not sure it's worth the long trip.
2) Should we spend a night at Plitvice? I'm considering doing this with Split Excursions as a day trip or possibly renting a car, although I am a little nervous about driving where we can't read the signs.
3) Any other red flags?
Suggestions much appreciated.
