We sailed on the Constellation August 16 - 30, 2008 on the 14 night Scandinavian and Russian cruise. Although there have been several reviews on this itinerary and even more on the ship, I wanted to voice some observations that haven't been made, and reinforce a few that I found to be important.
I've been on over 20 cruises with Holland America, Princess, and Carnival, and I can say the Celebrity Constellation was the nicest and most enjoyable ship that I've been on. Most notable was the overall cleanliness and state of repair. For instance, I didn't see one carpet stain on the entire ship. The carpets were cleaned twice during our 14 day voyage, with a dry powder extraction method. Fixtures were all cleaned and in good repair. Even little things that sadly we've become accustomed to, like graffiti etchings in bathrooms, elevators, or public areas - I saw none of that.
Celebrity does away with some gimmicks, in return for providing personal service that really counts. For instance, we didn't get the nightly cute animal-shaped towel sculptures in our room, but more importantly, our room was always promptly serviced, at least twice a day, sometimes three times, even when we deviated from our typical eating or sleeping schedule. Our steward was really on the ball.
Quiet, no ship roll or vibration, no elevator or facilities noise. Convenient - 1 floor down to gangway, 1 floor up to guest relations. Close to stairs and midship elevator.
