Here's what I've noticed about the reviews at Ohana.
They went through a spell where they were not so good, but I noticed that they got WORSE during the busiest times of the year over the past couple years. A LOT worse. Recently, they seem to be improving. I'm not sure if that's because they've "turned the corner" or they just do better during slower times. Or a bit of both.
We're there in early January. It was stupendous in january of '06 and was one of our "must go back" choices for this trip. The reviews gave us some worry, when making our ADR's back in June, but we decided to keep it, anyway. If they're as good this time as they were last time, they'll stay "on the list" for future trips.
