Royal Caribbean has added the projected date of Check-in opening to the Royal App.
After Countless questions as to When check-in will open, or why Check-in is not available for cruises within 90 days, Royal Caribbean, under the radar without announcement, has added the projected date for Check-in to be available.
It is located under the Personal Info tab (the little human shaped button) within the app. This is via an Apple Device, Android MAY be different.
At this time, it does not appear that there have been any changes made to the regular website.
