Passengers are supposed to be enjoying their vacation… not throwing punches in the customs line!

A massive fight erupted between two families at PortMiami on Monday after the Carnival Conquest returned from the Bahamas. Video shows chaos with luggage flying, stanchions knocked over, and people of all ages swinging as tensions boiled over in the debarkation area.

Carnival Cruise Line wasted no time responding. A spokesperson said: “We do not tolerate such behavior, and 16 people have been placed on our Do Not Sail List.” Lifetime ban issued — no arrests were made as neither family wanted to press charges.

This isn’t the first time bad behavior has made headlines at sea. Is it time for stricter rules, or just a reminder that some people ruin it for everyone?
