I hate long drawn out reviews so I'll simply provide our good and bad about the ship. The itinerary and weather, IMHO are not relevant to a review of a cruise.
Like the size of ship but a little long in the teeth, the conversion not withstanding, e.g. Our shower stall was corroded and moldy, sheets and blankets were dirty. Steward promptly replaced them but couldn't do anything about the shower. Cabin was certainly smaller than the S class. We split the bed into two parts. Don't remember each unit being that small. Plenty of storage.
Service and friendliness of all crew members were outstanding. Captain had a terrific sense of humor, put on a skit with the CD and gave two outstanding lectures something we rarely see.
Ship is beautiful and a pleasure to walk around the public spaces.
Food, always an subjective issue, was IMHO very good. Dinner choices, portion size and taste were excellent. On our last cruise on the Silhouette I found myself choosing from the "Available Daily" menu several times. This time, not once. Desserts, always my favorite, were very good. One exception was the shrimp cocktail. Four tiny, limp little guys in a large glass of lettuce. Service was professional and quick. I do seem to recall that on prior cruises there was music during dinner but not this time
Never went to the MDR for breakfast or lunch.
The buffets on a cruise ship are always a love hate affair. I HATE THAT THEY ELIMINATED TRAYS!!! Such a hassle trying to navigate plates, silverware and beverage with the small plates they use. Breakfast and lunch offerings were plentiful, hot and tasty. Good sandwich selection and as always the cheeseburgers were outstanding. As always also the waffles were OUTSTANDING. However, what they say is maple syrup is a slightly bitter tasting concoction. Not what we have seen in the past. Not Celebrity's issue was the people and an over whelming sense that they were on their own private yacht. Pushing, cutting in front of people, reaching for food with bare hands - you know the drill. Of a particular nuisance was people sitting, playing cards, reading and enjoying the views etc, long after they were finished eating preventing others from using the tables. Especially a pain on this cruise because the outside deck area was not usable due to the weather on many days. There were signs on each table but were in English; should have have been in English, Dutch and German, Russian, Chinese and so forth.
At the Elite level we did enjoy the internet, laundry and other perks. The evening cocktail was a nice thing as always. However, on this cruise they roped off the prime spaces in front of the windows for non CC passengers. We were restricted to an area inside these ropes. Suppose one could take their free drink and sit at one of the prime seats but was frowned on. No music as well. Last year on the Silhouette, the entire Reflections lounge was used for the CC cocktail hour. Live music was provided. A personal beef of mine was the restriction of Michaels Club. Every night we would walk by it and see maybe four people inside.
Liked the fact that every night the shows were at seven and nine. Easier to plan for then when they were at various times for the early or late seating. Captain and the CD did a Liar Liar skit which was hilarious. A Cirque du Soleil duo was outstanding the far from the normal cruise ship offerings. Unfortunately not all were worthy. A kid juggler was an embarrassment to the juggler and the poor guy he picked from the audience. Only one other music related note was a guy in ratty clothes, the DJ and a girl playing the Sax. Unfortunately, she only knew one song which she played over and over and over......
Neither my wife nor I had any spa services. Basic massages were much higher in price plus now there is a mandatory 18% gratuity levied. Canyon Ranch as replaced Steiner.
The real winner on this cruise was the ports. Norway was spectacular despite the cold and the wind and the rain and the fog and the, guess that is it.
