Royal Caribbean plans a major makeover of its 14-year-old Mariner of the Seas.
The cruise line will spend more than US $100 million on the vessel, the most it has ever spent refitting a ship.
Plans call for a 6-week drydock in Cadiz in March and April 2018.
After the renovation is finished, Mariner of the Seas will sail 3- and 4-day cruises from Miami FL. Currently the ship is sailing in Asia.
