What to do in Hawaii!

Hey everyone! So my family all lives in Hawaii and my mom and I moved away when I was only 3, so I’m not really a local lol. We go visit my family often but we don’t do tourist shit, mainly just stay at their house and party.

but… my sister in law and my husband will be coming with us in one month for a family event we have going on and it will be their first time. I want them to experience tourist-y Hawaii and see some cool spots!

What we already have scheduled:

-luau

-boat ride to another island and back

-parasailing

-snorkeling

Obviously I’m gonna bring them to some bomb ass food but if anyone has literally ANY suggestions for places to go, eat, etc pleaaaaase let me know!

Thanks!!

Edit: we are going to O’ahu, my family lives in pearl city but we will be staying at turtle bay
