I just played both the Plantation and the Experience at Koele on Lanai last week.
The Plantation is an excellent course, a bit different that the Coore and Crenshaw courses I have played. This is NOT a walking course. The cart paths are used to take advantage of the land, its views and make best use of the eye candy this property has to offer, and it has plenty.
The course plays very short on the down hill holes, real the course tips in the cart, and when it says to aim at the right or left edge of the fairway, do as it says, you get almost a slingshot effect.
Well worth playing, I liked Plantation alot.
One word of warning, the latter in the day you play, the longer your round will be. We teed off a 12:20 and finished at 5:45, just before dusk. I would try to play early.
The experience at Koele is a mountain course set in the hills of Lanai. The highlight is the 17th hole which has a 250 foot drop from tee to fairway, the highest I have ever experienced.
You have to take a ferry over there, about a 45 min ride+a 30 min mini van or bus to the course. So this is an all day deal. We took the 9:15am ferry, teed off at 11 and ate dinner at the pool of the 4 seasons and took the 7:45pm ferry back.
This is a pretty course, with lots of elevation changes, lots of water features, plantings, water lillies, etc. And they were well done. We enjoyed the course, the pace of play was good, the conditions were good and the island is interesting.
Would I play the course a second time, no. Would I play the Plantation a second time, yes.
