I don't think there is a more amazing view anywhere on the planet. The Napali coast with the dozen waterfalls you can see from your window is second to nothing. Easy walk to the beach, amazing pool, great restaurant, friendly staff - the place has it all.
My wife and I traveled with with our 2 kids and the grandparents...it was a pretty ideal setup. 3 quiet bedrooms, each with their own bath and balcony. Comfortable beds. Well stocked and very usable kitchen.
There are some costs that caught us off guard - such as the $24 a day hanalei bay resort fee and the 18% hawaii hotel tax. I thought I would mention them so future travelers aren't caught off guard. That said, I thought the price was very reasonable for what we got.
