I have 6 nights available to spend somewhere in Croatia that is within reasonable distance to Split where ultimately I need to catch a 4pm flight to Rome. Prior to that, I will be spending 5 nights in Split, then an 8-day cruise through the islands to Dubrovnik (I will briefly visit Brac and Hvar), and then return to Split. After the cruise, I am searching for a seaside, low-key location to just relax. Should I return to either Brac or Hvar or can anyone recommend another destination that is within reasonable distance to Split? I will be grateful for any advice. Thank you.
