The only cruse directors I remember, from all the cruises I have taken, were two.
One was the very first cruise we ever took. It was Carnival and the CD was the most annoying person ever. I will never forget him.."Karl with a K." Even his name tag said it, he was introduced that way etc..
The other one, also from Carnival was Cookie. He was great.
But, honestly I pay no attention to the CD's, they have no bearing on my experience.
I couldn't even tell you who the CD was on our Allure sailing in 2019 or our Voyager sailing in 2022.
