Can I modify reservations or pre-cruise purchases with the Royal Caribbean app?

Some reservations and pre-cruise purchases can be modified in the app before you sail. 

For dining or shore excursions, you can either remove a Guest or cancel the entire reservation (within the cancellation policy). For further modification, such as changes in date, time or party, you can either cancel and rebook the reservation, or visit Guest Services once onboard.

For beverage and internet packages, no modifications can be made in the app, but you can cancel and book a different package.
