On January 27, Oceania Cruises opened bookings for its 180-day long cruise set for 2023. The trip sold out within a day. Covid-19 may have halted cruise sailings, but that’s not stopping people from booking future trips, even if the voyages are almost two years out. This includes people who have never sailed with the brand before: 33 per cent of the bookings were made by new guests instead of experienced Oceania travellers. “Despite the challenges the world faces today, travellers are clearly bullish on the future and are embracing these new opportunities to travel the world and create lifelong memories,” Bob Binder, president and CEO of Oceania Cruises, said in a statement. Why do these 6 seats always sell out on the world’s longest flight? The number of new guests on the 180-day cruise and the speed at which it sold out reflects “tremendous pent-up demand”, Binder said. And apparently, 180 days out at sea isn’t enough for some of its guests. According to the cruise line, 20 per cent of its world cruise guests have decided to lengthen the voyage to 218 days. The sold out trip will span from January 15, 2023, to July 13, 2023, and will start and end in San Francisco. The “Around the World in 180 Days” cruise hits 96 ports in 33 countries, including Namibia, Argentina, the United Arab Emirates, Vietnam and Thailand. The trip also includes three days in Antarctica and 61 Unesco World Heritage Sites. Is Nobu Matsuhisa taking the dining destination trend to new heights? These sites include the Great Wall of China, the Valongo Wharf Archaeological Site in Brazil, the Itsukushima Shinto Shrine in Japan, the volcanoes of Kamchatka in Russia, the Singapore Botanic Garden and Glacier Bay National Park in the US. In total, the cruise will cross all 24 time zones across four continents. Guests will be spending their 180 days at sea on Oceania’s Insignia ship. The Insignia includes four restaurants, eight bars and 342 suites, accommodating a total of 684 guests. When spending so much time on board, the menu is naturally a prime concern for guests. There’s even plant-based options for the vegetarian and vegan cruisers. Spending half of the year on a ship may seem like a lot, but the Insignia has a variety of options to keep you entertained while you’re out at sea … … including a spa, gym, art area, putting green and casino. There’s even the obligatory cruise pool deck. Will Covid-19 spark a trend for personal submarines? Prices for the 180-day journey started at US$41,600 for a stay in the inside stateroom. This cost jumps up to US$155,600 for the owner’s suite. The inside stateroom sits at 160 square feet (15 square metres), while the owner’s suite spans almost 1,000 square feet. “The response to our epic 2023 around the world voyage clearly illustrates the enthusiasm that experienced travellers have for immersive and memorable travel experiences,” Binder said.
