Looking for a luxurious, immersive cruise where you won’t have to worry about disembarking after just a week or two? Regent Seven Seas Cruises just announced the longest cruise in the line’s history, an epic 150-day journey that will reach all five continents and call on ports spanning from Australia to Alaska and from Asia to the Antarctic aboard the 700-passenger Seven Seas Mariner.The 2025 world cruise — Away in Wonder — will set sail Jan. 7, 2025, from Miami and visit 97 ports of call in 25 countries, traversing three oceans and 36,295 nautical miles over more than five months. It officially ends in San Francisco on June 6, 2025.The epic cruise will also include two new ports of call for Regent — remote Robinson Crusoe Island off the coast of Chile and Muroran on the Japanese island of Hokkaido. As if that weren’t enough, the extensive itinerary will also include a three-day excursion into the Antarctic.Fares for the sailing start at $86,999 per person for a deluxe veranda suite and $249,999 per guest to stay in the ultra-luxurious Master Suite.Regent typically offers one world cruise every year, and they sell out quickly. In fact, the 2024 voyage sold out in less than three hours, despite fares that reached nearly $400,000 for two for the 132-night itinerary.The even more extensive 2025 world cruise, the longest in Regent’s history, should get similar attention when bookings open later this year on June 15.For more cruise news, reviews and tips, sign up for TPG’s new cruise newsletter.“We know that our guests are looking for extended travel in exotic destinations, which is why we are incredibly excited to unveil the longest World Cruise in our 30-year history,” said Jason Montague, president and chief executive officer of Regent Seven Seas Cruises in a statement.“Over 150 nights, travelers will not only experience the highest standards of service, cuisine and enrichment, plus enjoy a delightful array of luxury amenities, but they will also sail as far south as Antarctica, as far east as Asia and as far north as Alaska — all in one single, epic voyage as they sail Away in Wonder.”Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
