The Carnival Cruise Line cancellation policy has varied conditions depending on when the cancellation occurs. Passengers who cancel their cruise far in advance typically get a full refund less any non-refundable fees. The amount of the refund drops as the departure date draws near, and visitors could have to pay cancellation costs. Depending on the duration of the voyage and the time period, the penalties for cruises that are canceled within 60 days of departure are more severe and can range from a percentage of the total cost to the full amount.Carnival provides a “Vacation Protection Plan” that covers unforeseen circumstances such as illness or cancellations.  Â
