Stop along the way for beer before you get to aulani. Kapolei has a Costco, Target, and Safeway. We are not beer drinkers but buy bottles of wine along with a variety of breakfast and lunch food on our way to aulani. If you don’t rent a car most taxis or Uber will stop for you. Wine at aulani is about 9 to 12 a glass. Not sure about beer.
The four seasons next door has a happy hour from 3 to 5 with reduced prices on a few drinks including beer.
