Two months before this cruise we cruised Celebrity aboard the Century. The food was so good that when we had an opportunity to sail again we chose Celebrity again, this time the Millennium going to Alaska.The Millennium is a little bigger than the Century but not as nicely decorated or trimmed. Our first impression was the color of the walls and carpets and the plain decorating. Usually we get a balcony cabin but since we booked this cruise only 7 days before departure we took what we could get for cheap. As it turned out having an inside cabin did not bug us as much as we thought it would.Embarking went fairly smooth. Once greeted on the ship there was no greeting drink like on the Century. Apparently the drinks were available but on another deck level. You had to try to find it.One very nice thing that this ship does have which is great for the cooler Alaska trip is two inside hot tubs and a large hot pool. This area was very nice. The dining room food again was excellent. The menu was basically the same as the Century which was fine with me because they have great food choices.The dining service was also excellent. My only complaint is that on the second and last formal night after the waiters paraded the Baked Alaskan special dessert there was non left for our table. This was quite disappointing.Our ship came down with the norovirus which threw the whole ship in to a different safety mode. All of the salt and peppers were taken away, you could not dispense your own drinks at the buffet and all of the tongs were out of reach so only the crew could touch them. This caused a lot of back ups but I guess it is the policy when the virus hits. I don't know for sure how many were affected by the virus but you can check the CDC website in the future and it should eventually be posted there.The entertainment at the shows was not as polished or exciting as that on the Century two months ago. It was good but not great like on the Century.Also missing was a special brunch buffet that the Century had. This may have been cancelled due to the virus GI outbreak.Our room attendant was good and there were no problems here. The room was in good order though plainly decorated compared to the Century.We lucked out on this Alaska cruise as we had at least some sun on each and every day of our cruise which is not normal for Alaska.The naturalist on board was good at spotting whales and sea mammals and explaining the geology of the trip. He gave several lectures which are "interesting" but obviously of the Discovery Channel type hype.I was totally impressed by two of the entertainment staff. While exiting the muster drills Mike was greeting travelers and asking them their names. We told him our names as did several dozen others at least. About an hour later Mike saw us up on deck 10 during the departure and called both of us by name. This amazed me. Throughout the week when he saw us he continued to call us by name. There was another gal in the same position who did the same thing. We were very impressed with this.Several years ago we did a similar Alaska cruise with Princess which was a very good cruise. I would say Princess had better entertainment but Celebrity has the best dining room food out there.
