Fred Olsen Cruise Lines is sending Braemar, Balmoral and Black Watch into dry dock this winter in preparation for the 2020-21 season.
All three will receive new public areas and cabin improvements during their revamps, taking place from now until December 21 at Blohm+Voss shipyard in Hamburg, Germany.
In addition, a number of cabins on 804-passenger Black Watch will receive bathroom upgrades.
On Balmoral, an Oriental Room will be added on deck six, where teas and Far Eastern-themed cocktails and drinks will be served.
A photo gallery and flower shop will also be installed on to the 1,325-passenger ship.

Engineering works, general maintenance and other refurbishment will also be carried out.
Braemar entered dry dock on Thursday and will return to service on November 24 when it sales a nine-night French, Belgian & Spanish City Overnights cruise from Southampton.
Balmoral will enter the yard on December 10 before emerging 10 days later, while Black Watch will go in on December 11 and come out on December 21.
The line’s fourth ship – 880-passenger Boudicca – will go into dry dock in autumn next year.
Peter Deer, managing director of Fred. Olsen Cruise Lines, said: “We are very proud of our smaller, classic cruise ships and we recognise the importance of investing in ongoing upgrades to ensure that our guests can continue to enjoy them at their very best.
“Our refreshed and renewed fleet has been very well-received by both new and existing guests following the last round of improvements at Blohm+Voss in 2017 and 2018, and we are keen to showcase the latest enhancements to our guests before Christmas.”
