The Ko Olina Association puts on a 4th of July event right on the beach in front of Aulani. They construct a stage and have entertainment for most of the day. At night, fireworks are set off from the large rock area on the left side of the lagoon. It's great having the festivities so easily accessible, but in our experience, it's the most crowded day we've had at Aulani over many trips. The pool chair situation is challenging on normal days, but it seemed as if not one person left the property on July 4th. Very, very crowded...pool area and beach. Regardless, we had an incredible time. This was all pre-COVID, so I'm not sure if they will continue with that event this year. Perhaps a scaled down version.
