AKL is an astoundingly beautiful resort. There is much to see and do just touring around waiting for your meal. Last year we did the same thing you're planning. This year we're planning a two day stay before hitting the Polynesian. I imagine you'll be sold on it as well.
As stated above, there's so much to keep you busy the walk around the resort will be as memorable as the meal.
Boma, in the mean time, is excellent. Last year everyone was telling us about the "zebra domes" (don't worry, you eat them!) Well, I had two, and they are delicious, as is everything else I tried there.
You are in for a wonderful experience.
Bring a camera, you don't want to miss capturing this amazing resort on film!
