Just read this on RCCL blog:
The Loyalty 2X Points offer is valid on new bookings made between October 19 - December 31, 2020 to Gold, Platinum, Emerald, Diamond, Diamond Plus, and Pinnacle Crown & Anchor Society members.
Royal Caribbean updated the offer to extend it as well to existing bookings. The sailing must depart between January 1 – December 31, 2021.
Loyalty 2X Points provides Loyalty members 2X Crown and Anchor points on sailings departing on January 1 - December 31, 2021.
Crown and Anchor points will be applied once the guest pays the booking in full and completes the sailing. When reserving, a valid Crown & Anchor Society membership number must be included in the reservation.
The bonus provides an additional point per night of new cruises booked, which means staying in a standard stateroom would get you two points per night, instead of one.
The offer is not combinable with Standard Group, Interline, Travel Agent, Travel Agent Friends and Family, Weekly Sales Events, and Net Rates.
The Double Points offer also provides bonus points for guests who would otherwise qualify for bonus points:
Solo guests staying in a room by themselves would also qualify for an extra point, getting them three points per night.
Suite guests would also receive three points per night.
A solo cruiser in a suite would get four points per night.
