Regent Seven Seas’ Seven Seas Explorer is to be showcased in a four-part documentary on Channel 5.

Television crews were given access to the 750-passenger vessel – dubbed “the most luxurious ship ever built”, by the line – over two sailings around the Iberian Peninsula, the Bay of Biscay and Baltic Sea.

The first episode of The World’s Most Expensive Cruise Ship, due to air on Friday August 23, follows Seven Seas Explorer’s cruise director John Barron as he prepares to meet a new group of passengers.

Cameras will also capture head butler Raju as he prepares the top-level Regent Suite before a cruise.
