Why do you say that? I see that the T&C state that the program applies to cruises after January 1, 2023, but I have also heard on CC (which, of course, is not official), that previous cruises with OC would still count towards earned benefits.
Any why do we need to be discussing this at all? You would think that Crystal would make some mention of this in their T&C...although perhaps that's what the January 1, 2023 statement means.
