Having just been on a 15 day Royal Transatlantic, we expected the same level of cruising on her sister ship, the Royal. While the "facility" was almost identical, a number of things were lacking.
The quality and variety of foods in the Main Dining Rooms seemed below what was presented on the Royal. Even the Horizon Buffet was not quite up to par. When the buffet fails to please and you end up having Alfredo's Pizza for dinner, something is off. (Pizza was good, just not the reason that we cruise.) A lack of good alternatives to the daily menu was disheartening.
The cabin seemed identical and was clean. The bed was comfortable.
