The sailing which, at 150 nights is the longest in the cruise line’s history, had fares starting at £69,389pp for a Deluxe Veranda Suite, and £191,949pp for a Master Suite. The ship’s Distinctive Suites were the first to sell out with guests desiring higher accommodations.

"We have received unprecedented interest in this sailing and this phenomenal booking record shows once again that people, just like the world itself, are now open to travel and are not going to wait around and let opportunities pass them by," said Jason Montague, president and chief executive of Regent Seven Seas Cruises.

"It is remarkable that luxury travelers continue to sign up, or want to remain on the waitlist, in case some guests cancel their reservation between now and the sailing in two and a half years’ time – people simply want to explore as much as possible."

The Away in Wonder world cruise embarks on 7 January 2025 from Miami to San Francisco and calls at destinations in South America, the South Pacific, Australia, New Zealand, Asia and Alaska.

Guests will sail three oceans, visiting 97 ports of call in 25 countries on five continents and will cover 36,295 nautical miles over more than five months.

Travellers can also add an additional 18-night sailing to the voyage, with approximately 25% of guests taking this option. The additional voyage sails the Mexican Riviera from San Francisco to Miami, visiting ports in Costa Rica and Colombia along with a full transit of the Panama Canal.
