The anytime dinning was done in the midships dinning room and the assigned dinning was done in the aft main dinning room on the Dream. Same setup on the Splendor. I am not sure how they handle it on ships without a secondary dinning venue. My guess is the upper and lower level split. But if I remember correctly the Fantasy class ships do not have 2 story dinning rooms. So that may be completely different. Do they even have MTD on Fantasy class ships?
