Yes. Three of P&O Cruises’ vessels are adults-only; the Oriana, Adonia and Arcadia. On these ships, the minimum age for passengers is 18. Cruise and Maritime’s Marco Polo is another adults-only ship, though they will accept teenage passengers of 16 years or above if accompanied by adult passengers. Silversea does not recommend booking children on its cruises, while Voyages of Discovery does not recommend booking children under the age of 11 on any of its cruises. Thomson Cruises does not operate adults-only ships, but does offer adults-only sailings on a number of its vessels. A number of other lines offer adults-only areas on-board, such as Princess Cruises’ Sanctuary area and Carnival Cruises ‘Serenity’ area.
