Cruise do's and don'ts: Top 5 things that will get you banned for life

It was not smooth sailing for passengers on a recent cruise out of Galveston, Texas.

A Carnival Cruise spokesperson said the incident occurred in the debarkation area, which is under the authority of U.S. Customs and Border Patrol. 

"This matter has been turned over to law enforcement," said the spokesperson in a statement.

Duckworth added, "One of the top mistakes I see people making on a cruise is that they overindulge, especially with alcohol."

"This can often lead to unruly behavior and actions you may regret later," he said. 

Stewart Chiron, a Miami-based cruise industry expert known as "The Cruise Guy," told Fox News Digital he agreed that behavior on board is a top issue to watch for - and shared four other reasons passengers could get themselves banned from cruises. 

The smuggling of controlled substances and weapons aboard a cruise is a concern worth noting.

"Cruise lines have their individual codes of conduct and lists of banned items," said Chiron. 

"Cruise lines not only have to follow the laws of the countries they homeport from, but also the various countries and ports they visit."

He also noted that bad behavior, not just onboard but on shore, could be a problem.

Finally, he said chronic complaining could land people on the banned list.

"There are people that go on cruises and complain about everything and anything in order to attempt to receive some sort of credit or benefit," said Chiron. 

"These types of people have been banned," he said.
