The Independent reports Carnival Cruise Line had added a disruptive behaviour clause to its Cruise Ticket Contract.
Should a passenger breach the clause, they will not only be fined up to US $500, but could also be liable for other expenses incurred by the line as a result of their actions.
According to The Independent, the clause reads: "Any guest whose conduct affects the comfort, enjoyment, safety or wellbeing of other guests or crew will be detained onboard and/or disembarked at their own expense and will banned from sailing on Carnival in the future.
