We arrived an hour late for our last reservation at 'ohana. (It had been a rainy day, and we spent the afternoon relaxing in the room. We were going by the time on our Ipads that had not adjusted for the Eastern time zone change like our phones had! woops!) I was very certain that we'd lose our reservation, be charged the no-show fee, and it was just devastating because I had tried for three trips to get ressies at 'ohana and now it had come to this. Anyway, the point of my story is that our reservation was for a normal dinner time 6:30, and we arrived at 7:30. Upon arrival, I noticed on the ressie list that they had sat everyone else with reservations prior to 700, but they had not cancelled our seat thank goodness! (So to answer your question...) on that night, everyone appeared to be seated around their reservation time (within a half hour). And my other point is don't fret if you're a few minutes late. I wouldn't at all recommend waiting an hour, though. That was not a magical moment for us. Don't worry---a backscratcher and lapu lapu followed by Wishes! helped restore the magic. Since you are going at 6:30, I'd plan on viewing Wishes! from the beach at the Poly. It's really cool watching it there. And this way, if you happen to still be in the restaurant during Wishes!, you can view it from there. They even play the music. aloha!
