As regard the Elite Breakfast, being buffet or plated, back in the days when the revision to plated was made it was supposedly because the authorities weren't happy with self service counters in a carpeted area, which at the time was the case on both M and S class ships due to the then positioning of the counters. It is now possible on the S class only? to have mobile buffet counters at the polished floor entrance to Tuscan Grill - i don't think the same is possible at the venue used on the M class (long time since I've sailed on one) which may explain a previous comment...
