In September we were in Maui. We got a week long pass at Maui Ocean center. Highly recommend. If you plan ahead, you can get a 10% discount online.
Surf's Up! Erik learned how to surf in Maui.
We spent a lot of time at the beach. Instead of fighting the biological clocks, we just went to the beach almost everyday around 7 a.m. The kids were a lot more awake and there wasn't a crowd of people.
