At 14 and 16, your kids are past the character-meet-and-greet phase but not ready to be parked at the resort alone. Grand Hyatt Kauai and Andaz Maui strike the right balance: legit cultural programming (not dumbed-down), serious pools and beach access, and enough sophistication that teenagers won't roll their eyes at their parents' choice. Both lean into Hawaiian experience rather than theme-park energy. Skip the water-park-heavy resorts unless your family still wants slides over snorkeling and sunsets.
