Embarkation in San Diego was flawless. The cruise terminal is within sight of the airport, and a Rite-Aid drug store for last minute Cokes and forgotten toiletries is just a short walk away.
The ship itself is nice. It never felt crowded- much different than the feel of Carnival's Magic (for example). Food service was fine, with the quality and delivery of food in the dining certainly above average. The stateroom we had was in an excellent location- mid ship on the lowest level. Cabin service was excellent. Both the head and assistant cabin attendants were hard working and friendly. The view was very good, looking out directly on the waves. Seas were at most moderate, so there was almost no movement in our cabin. There were no annoying mechanical noises to interrupt our sleep. However, the room was small, making us believe the largest rooms for the money are on Carnival. We initially had no air conditioning, but the staff had that repaired in short order.
On-ship entertainment was average, with an above-average cruise director competently directing events. Celebrity does have a couple of unique offerings in its entertainment line-up. There was a string trio- performing both in the lounge and a classical performance in the theater. A concert pianist performed a couple of times in the theater. These were unlikely performers for the venue, but well-received by the large audiences attending.
Second deck- lowest deck for paying customers. Mid-ship. Quiet cabin with no irritating mechanical noises emanating from machinery they don't tell you about when you book the room. Very little cabin motion. Good view out of generous window.
