To start off, we were upgraded from a Sky Suite to a Celebrity Suite, and that set the mood for us...what a great cabin!
The ship is beautiful and very easy to navigate, despite her huge size.
The elevators are spread apart, and perhaps those who do not enjoy walking from one end of the ship to the other might wish for midship elevators. We did not mind.
All of the dining venues are aft, with the main dining room covering decks 3 and 4, and with the specialty dining on deck 5.
Because of being in a suite we were offered 2 nights of specialty dining. Had it not been complimentary, I would not have felt the need to eat outside of the dining room. The food and service were excellent. Interestingly enough, people on cruise critic had complained that the Silhouette Dining Room was noisy. We did not find this to be true, but found the Tuscan Grill to be VERY noisy. The dining experience in both Murano and Tuscan were fine, but not worth an upcharge, in our opinion.
The cabin, which is 2 rooms comprising a separate bedroom and living room, was just lovely, and our butler, whom we did not use very often, was extremely willing to be of service.
The entertainment, for the most part, was just that...entertaining. The comedians were funny, the dancers adept, the cirque-like performers quite agile, and the singers were musically talented. There was one show, called Junk, that utilized some British youths playing various garbage items as though they were instruments. This show did not go over very well with the majority of people we met on the cruise. We didn't find it as objectionable as they all seemed to, but this was probably an age thing. The musical group just wasn't geared for the 70s-80s crowd.
That brings me to age. My husband and I are in our lower 60s and skewed to the young end of the spectrum. Whether it is the itinerary or the length of the cruise, most of the guests were beyond senior citizens. Again, not a factor for us, but anyone wanting a young lively group is not going to find it here.
The first week of weather was quite chilly, and the second week (at sea) was very pleasant and warm.
We had some heavy mistral winds in the Mediterranean and one night there was enough turbulent boat action to break some of the partition glass and soak a few cabins on the lower decks.
The service throughout and at all levels, was friendly and accommodating. Everywhere you went, staff and crew smiled and offered greeting.
We first sailed with Celebrity back when they inaugurated the Zenith and the Horizon. The food quality was borderline luxury cruise back then, and has become more mainstream banquet. Still was very good. The buffet at the Oceanview was designed well, and lines moved quickly enough. The food was just ok buffet style food, however. We could not see using the Oceanview as a substitution for the dining room.
The enrichment lectures they offer on transatlantics, to be honest, were snoozefests. We tried 2 and both were boring as watching paint dry.
Overall, it was an excellent experience, and we would not hesitate to sail with Celebrity again, though I think we slightly prefer Holland America.
