This was our 3rd Celebrity cruise (first two to Caribbean)and we have mixed feelings about the Century. It is a smaller, older ship than the Constellation and Equinox that we previously traveled on and it had some pluses including a warm and pretty Dining Room as opposed to the huge, stark space on earlier ships, however we missed the wonderful upper decks with the green lawns and long walking areas. Walking on the short decks had bit of a tugboat feel. The casual dining area where most meals are taken was a disappointment with the same selection every day for breakfast and lunch--and the desserts were mostly small, ubiquitous gelatin-mousse concoctions which are pretty but mediocre at best. Dinners in the Dining Room were somewhat better. A plus: the Century has more storage space than other ships--3 closets!
However, the Naturalist on board (Miles) is wonderful and so is the Cruise Director, Sue. In fact, the large theatre entertainment was perhaps better than on the larger ships. But there are fewer additional musical and other entertainers--however, a great male quartet if you could catch them. The spa area has a great fitness center on Celebrity ships. You can walk on the treadmill or the bikes "across the water" or so it seems. The spa had the usual seminars pushing products--esp the de-toxification system and it gets pretty irritating after several cruises. (You subscribe to the product which is expensive and it supposedly causes you to lose weight, gain energy,etc.) This time we did not use the massage or beauty salon but we have in the past and they are fine.
We enjoy Open Seating dining for dinner and had some difficulting securing it but it was made possible at the last minute which was appreciated. You meet such interesting people from all over the world, especially in the dining room. Since it was summer, there were quite a few children on board and it was fun to see how well all the kids got along even tho they were speaking several different languages. We watched the Olympic Opening Ceremony in a lounge with l000 other people from many different countries and that was special. As with other cruises, our only real criticism of Celebrity is the surprisingly bad customer service. My email prior to the cruise inquiring about temperature and dress was not returned until after we returned home and Guest Relations on the ship has always been indifferent to rude. However, the restaurant and cabin crew are absolutely wonderful on every ship.
Re: Alaska. It was more spectacular than anticipated. We esp enjoyed visiting the land-locked cities and learning about the people and their lives. The Mendenhall glacier tour is a must. We went on at ATV tour at Icy Point which might be fine for 30 year olds but it was extremely bumpy and exceedingly dusty and dirty. Icy Point is just beautiful. From the map we were given, wasn't sure I even wanted to get off the ship as it looked like just a couple of tourist stores but the stores had great jewelry, clothing, good food and there is a wonderful bar/lounge at the bottom of the zip line (which looked fun.) Be sure to walk along the beach trail. We saw a whale a few feet away which jumped totally out of the water--and only saw some quick, black objects jump on the rest of the cruise. Incidentally, some people wore parkas and others standing next to them wore shorts and sandals. Take a jacket but it doesn't really get cold.
