This ship is way past it's "sail-buy" date. 5* Standard it is certainly NOT!! Twenty previous cruises including two with Celebrity gives us some standards on which to base this review.
Upgrade package to Aqua-Class was to give us more 'perks'. Aqua- Class cabins are either on level 9 or 11. We were allocated 9072. I quote from Celebrity's official web-site.
"In addition to a newly enhanced spa and wellness programming, you can continue to experience our luxury AquaClass® accommodations, which infuse your stateroom with additional spa-like elements and more."
