Unless you play each course twice, you'll wake up one morning in a cold sweat, saying "I wish I could have played that one a second time."
If you love the notion of template holes, you'll want to get on Old Mac twice.
If you love the ocean, you'll want to get on both Dunes courses twice.
If you love quirk and diversity, you'll want to get on Trails twice.
If you can play a big course in the morning, followed by The Preserve in the afternoon, it's better on the soul, I think.
I've not played Shorty's, but I have gone round half of Punchbowl. If you have an hour in the evening, do one of those two.
