We have a car when we visit and enjoy exploring off-resort for food to a degree. The lack of food variety hurts Aulani for us more from a convenience factor. After a long afternoon out, sometimes we don't want to venture out again for dinner. Olelo room frequently has long waits due to the small size, I have no need to do the luau on a trip 6 months after the first, 'AMA 'AMA isn't open right now, and we didn't think Makahiki was very good. Pool food gets repetitive quickly. We stayed for 8 nights and the food situation got boring fast, even with daily excursions out. I don't want to have to leave for both lunch and dinner most days... that is annoying.
For the luxury status of the resort, I would just expect more/better food options. It isn't deal-breaking for staying at Aulani (clearly since we are about to go back) but it is a real inconvenience of the resort that I feel warrants being called out.
