I played the Makai back in November, and they had fencing with green sheeting blocking the Prince hole corridors closest to the Makai course. According to the Makai starter they were working on refurbishing to re-open in 2024 as a private course, and it was going to be totally separate from the Makai course/membership...not related at all. The discussion had the vibe that the starter thought it was a major letdown that the locals and longtime Makai employees won't get to check it out after it was originally public then closed for so long. I feel his pain, as Kauai is a small rock and Princeville is a remote community on a small rock.
Before our trip I searched quite a bit about the course (I played it 20ish years ago), and certainly didn't see that it ever opened in any fashion since it's original closure...but I also didn't see any online plans for a reopening of any kind either, so that was news to me.
