Ko Olina golf course is a great course. Played it 5 years ago. Stayed at the Aulani (Disney Resort) which is right across the street from the course. Still have a Lotte LPGA hat that I wear. The black swans at the course are cool.
We brought the head Pro some Cape Cod lobsters and he gave us a good deal on rental clubs and rates. We were there in the dry season in January and since Ko Olina is on the leeward side of Oahu the course played very fast with lots of roll.
Played with a Japanese father and son who spoke no English. There was lots of nodding and smiling. Great time.
