SOUTHAMPTON-based P&O Cruises has announced its vessel Oriana will become an adults-only ship at the end of next November.

When Artemis leaves the P&O Cruises’ fleet next May the number of holidays exclusively for adults available within the company’s programme will be effectively reduced as Adonia, her replacement, is smaller.

A P&O Cruises’ spokes-man said: “We therefore wish to add a third ship to offer this type of holiday.”

From December 2011, Aurora, Azura, Oceana, and Ventura will feature a wide range of family friendly facilities, and Adonia, Arcadia and Oriana will be exclusively for adults.
