We booked Aqua class, as had done several times before. Not worth it, and for much less, you get almost the same in other categories, like Veranda or Concierge.
Blu restaurant was always full, had to wait 15-20 minutes every evening, no matter what time we arrived. Breakfast is available between 7.30 and 9. Good but very slow. Seems they are short on personnel. Menu not as good as it used to be, fewer options. Much better options in the main dining room.
Ocean View restaurant is good, with many different options, opened most of the day.
