No idea who the CC hosts are, didn't care to search them out, I am on vacation.
If they advertise they have an event and when we went and it wasn't there, well ok too bad.
We always went on our over 30 Celebrity cruises to the CC Elite Plus and above cocktail events. Warm passed appetizers and more importantly usually spoke to other interesting guests.
When they dropped and only partially maybe reinstated it, just one more reason to just ignore the Elite plus member invites. At least for us no longer much value in these.
Others may have a different view.
