Port of call was canceled because the ship's engines were not mechanically ready to perform at full power, which as every sailor knows is the captain's responsibility.
Horny crewmembers unable to cease from ogling/hitting on underage girls and sexually harassing both passengers and other crewmembers (perhaps a name change, Carnival? "The Lust Boat"? Or the "Lusty Rust Bucket"?).
Getting anyone at Carnival to apologize for or even admit the egregious conduct of their crew is like pulling teeth, again, captain (and CEO's) responsibility.
