Aqua Class was a big improvement over some recent sailings. We liked our cabin 1115- a little newer, fresher, no urine or sewer smells in the bathroom. Convenient elevator to Blu dining room. Also, enjoyed deck 11 in general. We had an excellent room attendant.
Things we loved about Blu: serene, subdued lighting, quiet, plush, beautiful, attentive staff, food overall quite good.
What I really disliked about Blu: very, very slow. Most evenings it took at least 1.5 hrs from the time we sat down until the main course arrived. With such a port intensive itinerary, we were very tired and didn't want a long, drawn out dining experience night after night. In contrast, the Main Dining Room is bright, loud and quick.
Excellent, no noise, no smoke, convenient to Blu.
