Every year for our World’s Best Awards survey, Travel + Leisure asks readers to weigh in on travel experiences around the globe — to share their opinions on the top cities, islands, cruise ships, spas, airlines, and more. Readers rated islandsaccording to their activities and sights, natural attractions and beaches, food, friendliness, and overall value. What all of the destinations on this year’s list have in common is a decidedly laid-back vibe.
