Its fun to play without much trouble.

Definitely play Koolau. Feels like you are playing through the jungle. Had a wild pig come out of the bushes about 5 feet from me as I was about to hit. Scared me to death.
Luana Hills CC is also fun to play with the same feel as Koolau (now the course is called Royal Hawaiian Country Club)

Coral Creek was also a fun easy course to play out in Ewa Beach.

Turtle Bay Palmer course is a good one too. Fazio course out there is just blah. Though I wish both course would give you more ocean views
