I worked on Canberra for ten years - she was lovely! My husband joins QM2 in June or July. Why not ask for a special piece of music to be played on the Radio?
Given the number of passengers on board it is the only way the catering can be handled give there are so many meal options all day. Try and find out if there is a casual dining room and if so use this on alternate nights with dining in the Princess room at the 1st or 2nd sitting on those special nights and to add when we were on the QE2 The P1/2 was fantastic for service and quality of food. Enjoy your anniversary celebration.
