We just got back from Aulani on Sunday. It was absolutely Beautiful! I'm sure you can get groceries delivered from somewhere, but, since I'm assuming you will have a car (you'll need one), there's a town about 4 miles before Ko'Olina with a Costco, a Safeway and a Target. You can get all you need between the three of those stores. There is not a meal plan, and really, not that many DVC perks. Parking is free, though, which is nice. By the way, the refillable mug used to be somewhere around $32 for the length of stay, but Disney brought it down to $18.99. Very reasonable. And, the mugs are much nicer than the WDW refillable mugs.
