P&O Cruises’ 21-year-old ship Oriana is to be refurbished later this year.
A three-week refit of the mid-sized ship is to take place in Hamburg in November.
Work to the 1,870-passenger adults-only vessel will include cabins, restaurants, bars, entertainment areas and public spaces.
The objective is to provide “a whole new elegant and sophisticated look,” according to the cruise line.
P&O Cruises is collaborating with design firm Richmond International, which worked on the decor for flagship Britannia, which was launched last year, and various luxury hotels, to provide “a modern yet classic look and feel throughout”.
Oriana’s last refit was in 2011 when it was converted from a ship for family cruising to become adults-only with 27 cabins added.
P&O Cruises senior vice president, Paul Ludlow, said: “After listening to guests’ feedback, we are investing in updates to many areas of the ship, but what is key is that we are retaining her unique charm and traditional character.
“With her teak promenade and lido decks, we know that Oriana holds a special place in the hearts of many of our guests and so we will be keeping her most distinctive features, such as her Tiffany glass ceiling and other well-loved classic touches.”
