Luxury cruising, with its high-end amenities, state-of-the-art ships and over-the-top service, accounts for only roughly 4% of the overall cruise industry, but it is quickly growing, projected to reach 1.2 million or more annual customers by the end of the decade — double the numbers from 2019. And travelers are now taking these luxury cruises to all corners of the world, exploring everywhere from the Kimberley in Northwest Australia to the Falkland Islands; from Greenland to Fiji, and of course, the fastest growing destination on luxury bucket lists: Antarctica. Last year, roughly half of new cruise ships were these smaller luxury vessels. Peter went aboard the newest luxury ship, Explora 1, for a report — and to discover the changing definitions of the word “luxury”, not to mention other terminology.
