Grand Wailea and Grand Hyatt Kauai dominate here because they nail multi-gen logistics: one parent can take kids to the water slides while grandparents relax poolside, then everyone meets for dinner without feeling like you booked separate vacations. Grand Wailea's water-park setup is unmatched for keeping different ages engaged; Kauai's kids' club buys you real breathing room. The Andaz is the smarter money play if you want refinement without the waterpark chaos. Aulani's a wildcard—brilliant for young kids, shallower value proposition for teens and grandparents.
