Background: We took a standard balcony. Married, early 60's, with numerous annual cruises on multiple lines from Carnival to Seabourn. We selected this cruise for the itinerary, not the ship or line. Short version: Celebrity remains and excellent choice in the so-called "mass marketing" cruise lines. Positives: Service and guest care, room, and itinerary. Negatives: Dining room closed for lunch, major reason to avoid. Fixed dining only in dining room.
Specifics: Boarding: (4/5) Pretty standard and efficient considering most guests were there an hour or more prior to earliest time. Keep in mind that on all larger ships you can go right on with no waits by showing up about 1.5 hours after the earliest listed boarding time.
Stateroom: Everything you would expect for a ship of this class with excellent service in every regard. Well maintained stateroom that was of average size for this class ship. Common areas: Not the best use of some space, but clean with no excess wear. Again, excellent service.
