In Volume 2 of The Confidential Guide to Golf Courses, Tom Doak published that.
“The original Mauna Lani course was expanded to 36 holes by splitting the baby and tacking on nine holes at the far end of each of the original nines. It’s hardly the ideal way to expand a course, because it’s difficult to give the courses their own character when you are trying to blend them with the older holes. The North course was my favorite of the two, because the new terrain is in older, chocolate-brown lava, and there was more topography to work with. The odd shapes of the greens create some interesting hole locations, and some awkward ones.“
The North Course at Mauna Lani Resort received a score of 5 out of 10 from Tom Doak and a score of 5 out of 10 from one of his co-authors.
