We've been fortunate to have a great cruise experience on each of our 3 cruises. However, Celebrity seemed to offer a high class of service and provided a much more relaxed experience that either Royal or Disney. Maybe it's just because we are getting older and aren't looking for a party on our vacations? But even our 11 year old son thought that this cruise topped them all.
The ship was tastfully done and had the feel of a high quality hotel and resort. Although the ship was full, the ship was always clean and there was never a feeling that we had just shared a space with thousands of people.
All of the food was great and we highly recommend Murano, the French inspired restaurant, for a date night without the kids. The was food was fantastic and the service was out of this world. We've had some great meals in Seattle (Campagne, the Metropolitan Grill, etc) but even they could learn a thing about service compared to Murano.
I can't remember but I think it was 6240. Our room was quiet!
