Promotions for the maiden cruises of Royal Caribbean’s next brand new cruise ship, which will be named Symphony of the Seas, are now being displayed onboard other members of the line’s fleet, according to media reports.

Royal Caribbean has stuck with the name around two months after it was accidentally posted on social media and therefore revealed by one of the firms involved in the ship’s construction at the STX France shipyard in Saint Nazaire, France. Photos showing the name emblazoned on the base of the hull accompanied the post. Despite being quickly deleted and the firm hauled across the coals, the name went viral among cruise enthusiasts around the world.

Upon its launch next year, Symphony of the Seas will carry just shy of 5,500 passengers at twin share and over 6,400 at maximum occupancy. It will be the fourth Oasis-class ship in the fleet and will be just a whisker larger than fleet-mate Harmony of the Seas – 28 cabins larger to be exact – which launched in April last year.

The other two members of the Oasis class are the ever-so-slightly smaller Oasis of the Seas and Allure of the Seas.

Symphony of the Seas isn't yet finished but will be a sister ship to Harmony of the Seas, launched last year.

Cabin reservations will go on sale from tomorrow, March 8, but at this stage only to guests currently onboard other Royal Caribbean ships as part of an incentive to existing passengers. No word has been advised yet on when cabins will be available to book more widely.

The maiden voyage of Symphony of the Seas will be, at this stage, a seven-night Western Mediterranean cruise, sailing round-trip from Rome and departing on 14 June 2018. It will visit Naples, Barcelona, Palma de Mallorca, Marseille and Florence before returning to the Italian capital.

This voyage will run weekly until early October when the super-ship will cross the Atlantic to its new home in Miami, Florida, where it will complete the 2018/19 peak northern winter season sailing alternating Eastern and Western Caribbean cruises until the end of April 2019. Its deployment there will mean Royal Caribbean will have all four of the world’s largest ships all sailing from eastern Florida.
