We've sailed Celebrity many times now, and we can tell you the experience is much quieter and far less action-packed than we've enjoyed on NCL. Of course, there's a disco and lots of bars and lounges ... evening shows ... even the occasional deck party. But the crowd seems to be older, more-seasoned cruisers who don't want a lot of craziness nor the crazies that create it. It's great that the cruise industry offers something for everyone, so just be clear with what YOU enjoy and choose your line and ship accordingly. That said, Celebrity is a very high quality product in terms of food, service, cabins and live music -- but it's definitely NOT similar to a Royal Caribbean, NCL or Carnival experience.
