I figured it out. They were never on Maui. No one goes to Maui and just stays an eats all their meals at a resort. No trips to Lahania, no sunrise on Haleakala, no road to Hana, no whale watching. It wasn't just the family, it was all the quest.
And a guest kills a staff member, another is violently robbed, yet no police.
The only solution that makes sense...it's Westworld.
