I realize I may be crucified for saying this but at some point years ago I got this saying in my head, I can't remember if I read it, someone told me or I heard it from a comedian. 9 holes of golf is like sex without an orgasm...
Somehow it's actually semi tainted my outlook in that when traveling to play great courses I've never stopped to play a 9 holer and perhaps even worse, not far from my home are a couple supposed quite nice 9 holers one being a links gem. I've not really ever thought to myself, he I should go play those. I'm sure any of you will say it's a mistake, although I do have to say if the course was so varied as some that you mention then it actually might be very interesting if the architecture was good enough. Hell, I might even reconsider the saying in it's entirety.
