Billion Pound Cruise will be shown at 9pm on More 4.

Filmed in late 2019 by James Corden’s company, Fulwell 73 Productions, the episodes highlight the world’s biggest cruise ship, Symphony of the Seas. 

Royal Caribbean’s vice president EMEA, Ben Bouldin, said: “This series was filmed at the end of last year, so we recognise that when we do return to sailing, it could look slightly different due to the introduction of our new Health & Safety protocols. 

“However, we are determined that what won’t change is the extraordinary and memorable holiday experience that Royal Caribbean International offers the whole family. 

“The show is a real ‘feel-good’ watch and we anticipate it will drive further awareness and consideration of the category as a whole and actively dispel myths about what it’s like on board the world’s biggest ship.  

“We’re extremely optimistic for 2021; we will have some incredible ships right on our doorstep including Harmony of the Seas - Symphony’s sister ship - which will be sailing from Barcelona from April next year.”
