Not completely accurate. If new CR patron makes prime during November 2022, they do not receive an annual tier benefit (free cruise) until a few weeks after April 1, 2023, and must sail by March 30, 2024.
When you call, realize that if your comped cruise offer code does not provide for a cabin category that supports 3 people in your cabin, then to add a third person, you will have to pay an upgrade fee to be placed in a cabin that does support 3 passengers.
