My third cruise on Century and I feel the ship shows it's age compared to other Celebrity vessels. While some people enjoy the smaller size of the Century, it lacks features found on the larger ships. I especially missed an indoor pool on Century. A lot more noise/cavitation from the props on this ship vs. the pods on more modern ships.
I met many extremely friendly crew on the ship -- especially in the Crystal Room "elite" happy hour and the Hemispheres continental breakfast. They work very hard keeping up with some guests who drink like fish (e.g., multiple double-shot Bloody Marys every morning for one old codger).
I was told the average guest age on the cruise was close to 70. It seemed much higher than on any Celebrity cruise I've taken before. So many wheelchairs and walkers -- it could have been Holland America! It's a less than terrific guest experience when an already fairly full elevator is packed even fuller by people who can't wait for an empty elevator (or take one or two flights of stairs). Anyway, enough ranting on some of the oblivious/rude older guests.
The Hawaiian ambassador and ukelele players were terrific, as were the Polynesian dancers at Honolulu. Some entertainment was good, such as the magician and violinist; however, there were some really foul acts as well. A husband & wife rock music/comedy act was dreadful. The "Dancing with the Officers" event was good fun. Rich, the cruise director, was quite funny MC'ing various events.
Murano was enjoyable, although the menu was old & due to be updated soon. Their "butterfly service" was less crisp than I've watched on other ships. Not a huge complaint at all, but timing was just a little off for no reason.
MDR has way too many large tables vs. tables for two. Sure, some guests want to eat with eight complete strangers and be bored to tears with bragging about how many cruises someone has been on, etc.; however, I think Celebrity should poll guests on preferred table size. I think more small tables would be much appreciated. On this cruise, the old folks all wanted to eat early, so first seating was quite overbooked & select was full, so that left second seating or the buffet (which was very good). The ladies really enjoyed the complimentary rose buds on Valentine's Day. By the way, many lovely flower arrangements around the ship in public areas, restrooms, Murano, etc.
