I am planning on playing Mauna Kea a couple times. From what I have seen it looks to have generous fairways and large greens. I only saw a few of the holes though. I enjoyed Hapuna but was annoyed by how claustrophobic it felt at times.
An aside about Hapuna. On a very quite day on the course I got caught behind a regular group on my back 18 that played in over five hours. To top it all off the sat beside the green, for I kid you not, ten minutes counting up their scores. Had the weather not been so great, I might have minded.
Has anyone played Kohanaiki and do they allow any non-members?
