Voyager Club

I am a member of the Voyager club and will be taking a cruise in January 2023 again, that has already been booked and fully paid for.

I received an email stating that if I don't book & cruise before 22 January 2023, my previous points will expire. My, already booked and paid cruise, is on 30 January 2023 - this seems unfair to lose all my previous points for just 8 days???
