Luxury Hawaii resorts for families don't have to choose between water-park thrills and actual relaxation. Aulani and Grand Wailea are the anchors here: one leans Disney (character moments, engineered fun for younger kids, calmer beach); the other is an actual water park masquerading as a five-star resort. Grand Hyatt Kauai and Andaz round out the range—pick Kauai if you want a true kids' club with Hawaiian programming and snorkeling, or Andaz if you're after design and a slightly lower bill without sacrificing the pool scene.
