This has been mentioned numerous times in this thread already, but Old Mac is the best example of this for me.
I've played it 4 times now, and the first 3 I really didn't care for it.
The big thing that changed during my 4th play was that I played it in the Summer - all of my previous rounds there had been in the off-season with pretty heavy wind.
This ended up making holes like the long par 4, 4th absolutely brutal. Once I played it with the wind blowing in the direction the way the course was designed, I had a newfound appreciation for it.
And I wonder for how many golfers their dislike of the course might be due to similar reasons?
It still isn't my favorite at the resort, Trails gets that designation, but assuming I'm playing during the summer months - it's one I'm much more excited about looping these days.
