So you fancy a seriously long cruise, and have loads of money?

Regent Seven Seas Cruises has announced its longest world sailing to date - if you are prepared to wait almost three years. 

The Seven Seas Mariner will depart from Miami on January 10, 2026, for the world cruise, named The Sense of Adventure. 

Guests will cruise three oceans over 154 nights and dock in 41 countries.

The itinerary spans the Americas, South Pacific, Australia and New Zealand, Asia, Africa, and Europe, Travel Mole reports.

The world cruise visits three new off-the-beaten-track ports – Lifou Island, Maré in the New Caledonia archipelago, and Waingapu in Sumba in Indonesia.

“We are excited to announce our newest and longest world cruise for 2026,” said Andrea DeMarco, president of Regent Seven Seas Cruises.

There is a choice of 431 included shore excursions and 16 in-port overnight stays.

These include Bora Bora; Darwin and Walvis Bay, Namibia.

The itinerary provides access to 47 UNESCO World Heritage Sites, including Robben Island off Cape Town.

Before boarding Seven Seas Mariner, guests will enjoy a one-night pre-cruise stay in a luxury hotel in Miami, and an exclusive pre-cruise gala event.

Fares for the 154-night voyage start from £79,219 $AU144,000 per guest for a deluxe veranda suite and reservations open on March 22. A pre-register period is now open.
