I heard about adults being rude to other fellow adult passengers, young kids running around the ship and bugging other passengers, kids bullying other kids, teens swearing and pulling pranks on cruisers ie stealing magnets, fish-xtender gifts, etc, 18-20 year old age range being rude in the adults only area as well as around the ship after midnight. I personally didn't witness this behaviour except for kids being very silly and running around the ship but to me that was typical kid behaviour and nothing that would stop me from sailing again or ruining my trip.
