To spend nearly half a year on a cruise ship is a life goal for some (less so for landlubbers), and nowadays, travelers have more options than a breakfast buffet. At least 10 major cruise lines offer months-long itineraries that circle the globe, and the routes continue to get longer, more luxurious, more in-depth, and yes, more expensive.

The all-suite, all-inclusive Regent Seven Seas has even one-upped itself with its latest announcement: In 2029, the recently refurbished Seven Seas Mariner will take 700 luxury travelers to all seven continents, stopping in 70 ports with 13 overnight stays in destinations such as Bali, Lima (Callao), Singapore, and Sydney. Billed as the “Eras of Exploration 2029 World Cruise,” Regent’s path will follow “the great arcs of human discovery—tracing modern marvels and ancient empires to seafaring legends and storied civilizations,” per a news release.

The 150-night journey starts in Miami, Florida, with an overnight stay at a swanky hotel and pre-trip gala, before setting sail for South America. The Seven Seas Mariner will travel through the continent, down the Amazon River, before making for Antarctica like modern-day Shackletons and Scotts. From there, it’s on to explore the rich cultures of Polynesia—including overnights in Bora Bora and Tahiti—before Australia’s Sydney Opera House beckons like a beacon.

After Oz, it’s over to Southeast Asia and the ancient temples of Bali and Thailand, then across the Indian Ocean to Mumbai in pursuit of stories of Indian dynasties. Arabian history gets its due at Jordan’s sacred Nabatean city of Petra, Egypt’s Luxor (Safaga), and the city of record-breaking skylines and superlatives, Dubai. For the final stretch of the whopping 37,000 nautical-mile trip, the cruise will overnight in the holy city of Jerusalem (Haifa) before departing for the Mediterranean coast, wrapping up in—where else?—Rome (Civitavecchia), Italy. 

“We are delighted to announce the latest iteration of our iconic World Cruise, which has been inspired by history’s most intrepid explorers and the paths of legendary adventures,” said Wesley D’Silva, president of Regent Seven Seas Cruises, in a statement. “The 150-night Eras of Exploration World Cruise will be an unforgettable experience that taps into the true essence of travel and adventure; we are looking forward to bringing our discerning guests onto this journey in the most luxurious and all-inclusive way possible.”

Let’s talk about those luxuries: Consistently ranked among the best luxury cruise lines in the world, Regent includes all shore excursions in the price—a fairly astonishing 326 adventures on this cruise. History buffs will revel in the dozens UNESCO World Heritage Sites visited, while foodies can check out the new onboard Epicurean Enrichment Studio, created by executive chef Kathryn Kelly as a chance to connect to the local cultures through cuisine. The culinary theater has programmed five key pillars: Epicurean Passport Series, Chef’s Circle, Chef’s Table, Chef-Led Epicurean Enrichment Tours, and Chef-Hosted Dining. Meanwhile, the suites have been refreshed as of 2025, including fully redesigned marble bathrooms for Signature, Grand, Mariner, Seven Seas and Horizon Suites.

Fares for the 150-night voyage start from $99,999 per guest for a Deluxe Veranda Suite, up to $344,999 per guest for a Signature Suite.
