Anniversaries and Birthdays celebrated at sea are meaningful and it seems all diners in the room enjoy the serving staff singing at the 'honourees' table. Although we've mentioned our b'day and anniversary in each booking made over many years, the experience has skipped over us; that is, until the suite life...then a lovely effort was made to decorate the cabin with balloons and petals on our bed. A card with flowers, chocolate strawberries, and champagne appeared signed by 'the cabin staff'. I asked who sent this, response was "It's from us...". This was very nice, however it was our son who had paid for the Anniversary package! I never had the heart to tell him the staff took the credit. I think any special marking of your personal event is dependent on the TA or X rep making the reference on your booking.
