In the tourism industry, unruly guest behavior has prompted the cruise line to update its contract.

A Carnival Cruise Line ship should be a place of relaxation and fun – but not too much fun.

Before spring break, the company informs customers that unruly passengers may face $500 fines and be asked to disembark.

Carnival’s updated cruise ticket contract states that passengers whose actions interfere with “the comfort, enjoyment, safety or well-being of other guests or crew” could be detained onboard and removed from the ship.

The contract also requires passengers to reimburse Carnival for expenses incurred by the detention or disembarkation of the ship.

The cruise line previously imposed a 1 a.m. curfew for under-18 passengers who an adult didn’t accompany.

Recently, the tourism industry has seen a series of inappropriate guest behaviors; fights have broken out on cruise ships, and passengers have gotten out of control on planes.

According to a Carnival spokesperson, “we don’t anticipate implementing these fines much, but when guests cross the line and disrupt others’ vacations, we will follow our guidelines.”
