Regent Seven Seas Cruises has unveiled details of its 150-night world cruise on board Seven Seas Mariner.
Leaving Miami, Florida, on 6 January 2029, the Eras of Exploration cruise will sail to Rome, taking in 31 countries en route.
From Florida, the ship will sail to South America and down the Amazon River, continuing south through The Drake Passage to Antarctica. From there it will cross the Pacific Ocean into Polynesia, on to Australia, Asia and Europe.
With 70 ports of call scheduled, guests can choose from 326 shore excursions.
On the list of 13 overnight stays are Sydney, Phuket, Lima, Bali and Rio De Janeiro.
The 700-passengers Seven Seas Mariner underwent a refurbishment in late 2025 with new furnishings and decor in all 350 suites and public areas.
Fares for the 150-night voyage start from £73,529 per guest for a Deluxe Veranda Suite.
The 2029 world cruise opens for reservations on 1 April.
