Celebrity is not really known for its parties, its usually much more of a laid back quiet vibe. There will be music at the pool during the day. Its not overly loud but they do sometimes have some activities out there on sea days. You can check your Celebrity app and it will give you a run down on the things going on during the day. I honestly can't recall seeing too many teenages on any of my sailings but I also haven't been on during spring breaks so you may luck out there too. Hope you enjoy your cruise! Its a great itinerary!
