When it was originally on TV, I worked nights and since it was in the pre-VCR days, I never saw it.  Now I watch it every Sunday on METV.  Boy, is it ever cheesy but I still watch it.  I guess you could call it my "guilty pleasure."  I like cruises so I like that it takes place on a ship.  I like seeing old-time stars near the end of their careers.  I like to see current stars near the beginning of their careers before they made it big.  It amuses me that on a weekend cruise, people meet and decide to get married after knowing each other for half an hour.  
However, I don't like the character of Julie at all.  I have calmed down a bit in my dislike of her; I no longer compare her to the Anti-Christ.  I guess I've mellowed out somewhat in my old age.  And I have to admit, although I hate to, that the show went downhill after she left.  It went from cheesy to absolutely ridiculous.  
I was never crazy about Vicki either.  She was a cute kid, but she got on my nerves.  Such a goody two-shoes.  I think they were trying to mold her into a mini-Julie.
