After 40 years of cruising, and 100+ cruises, I kind of agree with Lougee as well. In general, they neither make, or break a cruise. I often remember a CD when I see him, however I seldom remember their names. I do recall that when we sailed the Carnival Pride last year, the CD would hide from you when he saw you coming. I don't know if he was afraid you would ask him something about which he knew nothing, or what!! In any case, in my opinion, there are very few who are truly memorable.
