7 Days in Croatia - which island chose?

It’s doable. I assume you like to travel fast? Dubrovnik - Korcula - Hvar - Split are on a straight ferry line, so it makes sense, although you won’t have much time on either island. In this case, I might suggest 2 nights Hvar and skip staying on Korcula if you are looking for a bit more activity and the opposite if you are looking at something calmer and quieter. Both are beautiful in slightly different ways.

Then you will rent a car in Split and drop it in Zadar? You won’t need a car before this. Or maybe you are considering hiring a driver?

Then off to Budapest? I’ll add an answer on that thread.

Your itinerary is doable but a bit rushed with all the one-night stays. If possible, consider adding a second night in Hvar or Split to slow the pace.

Korčula offers a more historic, relaxed vibe. Brač is better for beaches and scenery. Korčula connects more smoothly with Hvar.

For the Split–Krka–Zadar leg, a private transfer is a great option. It’s much more flexible and comfortable than public transport, and you can stop at Krka at your own pace. Ivan Ćosić (MC-Travel Croatia) is a solid, professional choice for this route

I would just make it two nights on either Korcula or Hvar. From a raw sightseeing perspective there’s not a huge amount of difference between them, so give yourself a minute to enjoy the place. Brac is comparatively out of the way and again, kind of the same experience on such a short trip.

Thank you so much everyone. After reading all the comments and suggestions, I will definitely skip Korcula and stay 2 nights at Hvar. I think we will enjoy more and no rush.
