About Mariner of the Seas
Mariner of the Seas is the fifth and last Voyager-class ship, a second-generation design that entered service in November 2003 with American Paralympic athlete Jean Driscoll as her godmother. A month-long US$120 million refit in early 2018 added cabins and raised her tonnage to 139,863. Her 2026-27 schedule pairs a winter of Western Caribbean cruises from New Orleans with a 2027 summer in Europe, sailing Spain, Portugal, Morocco and Mediterranean itineraries from Barcelona and Lisbon, and transatlantic crossings in between.
