Adding Guests to an Existing Reservation Name changes (first or last) or substitutions can be made to all but one of the original names on your booking. These changes must be made before the final electronic manifest is sent to the ship, so we advise that any changes be made far in advance of your sail date.

Yes, you can generally change a guest on a Royal Caribbean reservation, but the "high-fidelity" rules depend on the timing and the specific fare type. Name changes are usually permitted until the final payment date without a penalty, as long as at least one original guest remains on the booking. If you attempt to change a name after the final payment window has closed, you will likely incur a change fee (typically $50 to $100), and the request must be made at least 48 to 72 hours before sailing to allow for manifest updates and security screening. Crucially, if you booked a "Non-Refundable Deposit" fare, the name change rules are much stricter and may be prohibited or require a full cancellation and rebooking. You cannot "sell" your ticket to a stranger and change both names, as this is viewed as a full transfer of the contract. Always contact your travel agent or Royal Caribbean directly to ensure the guest's name on the reservation matches their government-issued ID exactly to avoid denied boarding.
