Was on this itinerary Jan 20. Like your grading system! Agree with your grades for Ship, Crew, Room, Embarkation.
Curious as to why you gave food only a B+? We found the food in the Luminae to be very good as it was in the specialty restaurants we ate at (Eden for dinner and The Bistro for lunch). Had lunch one time in the OVC and thought the selection and quality were great.
Bars: Interestingly we found the Eden bar to have very good service and to be a quiet and relaxing venue. Martini bar? Overcrowded, loud and slow service. So my great would be a "B"
Entertainment: what shows did you walk out on? We had 3 cast shows, a comedian, a musical comedian, a magician, and a Motown group. Cast shows are what they are, generally great production values but sometimes a bit strange. None worthy of walking out on. The magician was the weakest of the rest and the others quite good. So A- on my report card.
Ports: sort of a been there done that thing for us. The ports are now so built up and have lost the local charm they had years ago.
