How to change or cancel a Royal Caribbean cruise
Whether you need to adjust your travel dates, switch itineraries, or cancel your cruise, Royal Caribbean has rules about making adjustments to your reservation.
Generally, as long as you cancel your cruise before the final payment date, you won't lose your entire cruise fare. After final payment passes, you will be subject to a cancelation fee, which varies depending on how far in advance you cancel.
If you need to change your travel dates or switch itineraries, there's usually a rebooking fee applied. You will also have to pay the difference in fare.
