Costco also has liquor (including the premixed margarita bottles available currently across the country) and is a 5min drive from Aulani. For those without a car, there is a "convenience store" across the street but definitely a price gouger. Still beats $10 drinks at the bar though.
For those interested in the USS Arizona, they only give out something like 500 tickets per day (they are free). In June, we showed up on a weekday maybe 20min after they open (7:30 I believe) and all tickets were already given out. I think the prepaid tours may count against this total so maybe we just picked the wrong day.
For those who have never been to Hawaii before, remember the time zone change- you will be waking up at 5am and ready for bed by 8pm the first few days you are there so plan accordingly (see some great sunrises and few people are at the lagoon early in the morning though).
Lastly, the "maze" at the Dole Plantation is a total waste. The train ride is okay especially if you have kids.
