Thinking of using one of my diamond suite upgrades, CapOne certs. and two free nights from the Hyatt card for a family vacation away from the ANC winter next January. From what I've read/seen it looks like the kids pool/sand area at the Maui Hyatt is a definite plus. But the Hyatt Kauai seems just a bit nicer and better-reviewed, while still seeming pretty kid-friendly. The weather averages look virtually identical at either location for January via weather underground. Any suggestions/recommendations would be appreciated.
