It’s the most unique shore excursion I’ve ever seen and it doesn’t cost a penny. We’ve just arrived at our first Croatian port, Rovinj, aboard the 315-passenger Wind Surf—one of Windstar’s distinctive sailing yachts and the largest in the three-ship fleet. The Ship’s executive Chef Ronald Waasdorp has invited guests to follow him to the local open-air market and 28 of us have taken him up on his offer.
