Must-do activities?

There is SO MUCH to do on the resort and I’m just wondering if I’m missing anything cool or should prioritize certain things.

We’re going to try to do the ukelele and drawing lessons (have some musical/artistic kids in the family), and I want to do the Māka’ika’i Art tour. Definitely want to snorkel in Rainbow Reef. The stargazing thing looks cool but is it $45 cool?

The spa is unfortunately out as my daughter (who started getting massage therapy due to a medical condition) is 13 and can’t go. I don’t want to go to the spa without her when I know she’d enjoy it. (Also BAH that they have services for 5-12 and 14+! Why?!)

We are also venturing off the resort a couple days (hiking, zipline, some museums in Honolulu which I will happily take recommendations on - oldest went to MoMA on a school trip and now wants more art).
