Embarkation was quick an uneventful, as it has been on all three Celebrity cruises I have taken. I recommend Aquaclass not only for the spa advantages and Blu dining but also for expedited check in.
Cabo San Lucas, and Puerta Vallarta were the only two ports worth visiting. We did not book any excursions. Personally you can only zip line, parasail, and lay out on a beach so many times before frankly you have just done it.
I personally though the Guatemala and Costa Rica ports were disgusting. Even the air risked of dirty.
Great view from our veranda, small compared to the solstice class line, closet was tiny, bathroom was tini tiny.
