Royal Caribbean International ship Symphony of the Seas will be showcased in a three-part TV documentary.

The first episode of ‘Billion Pound Cruise’ will air on Thursday at 9pm on More 4.

The series highlights the on board experience on the world’s biggest cruise ship.

The episodes were filmed in late 2019 and produced by James Corden’s company, Fulwell 73 Productions.

Featured elements include entertainment, ‘first at sea’ on board activities, cuisine and the crew.

The line’s EMEA vice president 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 and 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.”

He added: “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.”
