How to claim a Royal Caribbean cruise fare price drop
If your fare falls before final payment, you can often rebook lower or get onboard credit. Here is the step by step, by fare type.

Final payment is the line in the sand
Almost everything about capturing a fare drop comes down to one date: final payment, usually around seventy five days before you sail. Before it, you generally have room to adjust your booking. After it, your options narrow sharply.
So the first rule is simple. If you spot a drop, act while you are still inside the final payment window.
Refundable fares: rebook at the lower price
If you booked a refundable fare, a drop is straightforward to capture. Call Royal Caribbean or ask your travel agent to reprice the booking to the current lower rate, and the difference is adjusted on your reservation.
Because refundable fares carry the most flexibility, this is usually a quick, low friction change.
Non-refundable fares: ask about onboard credit
Non-refundable deposit fares are stricter, but a drop is not always a dead end. Depending on the current promotion, Royal Caribbean may offer an onboard credit adjustment rather than a straight repricing.
It is worth asking. The worst case is the answer is no, and you have lost nothing by checking.
Catch the drop while it counts
None of this helps if you find out about the drop after final payment. That is the part people miss, because watching your own fare for months is tedious.
Royal Radar tracks the fare on your sailing and alerts you the moment it falls, so you can make the call while the window is still open.
