We were also on this short trip.
All of my now 49 cruises have been with Cunard and this was by far the worst for service.
Main dining room food was luke warm at best, and the food choices are now very small compared to how they once were.
King's Court seemed to be fine.
Had a drink in casino and chart room and both didn't taste great like the glasses still had some kind of detergent in them,asked my wife to taste it and she said the same.
They seemed to of got rid of my favourite drink London pride in most bars.
Did I know it may be a bit of a trial run..yes..was it ..yes ,will I go again ..yes, but things need to improve going forward.
Our steward on deck 8 was great and had no problems.
