Not necessarily, but MickeyNicki may know more than I do. We tend to go EARLY, so it really may fill up later. We had one ADR for one morning, but then we also decided to go again spur of the moment on another day. No problem, but we were probably there when the place opened.
We were actually told that if you didn't have an ADR for dinner, just show up at 5:00 and they would work you in. I cannot say enough good things about the CMs in and around the AKL. Top-notch.
