I don't consider the Hemmeter properties luxurious by any means. They seemed to more go into self-contained family properties. I stayed at all mentioned here early in their openings and would say the changes since have been to make them more self-contained properties that families never need leave, with additions of water slides, spas, kids clubs and wedding facilities. I don't think of them as enhancing their surroundings, but detracting.
The true luxury and genteel hotels were/are the Moana and Royal Hawaiian and bungalows at Mauna Lani as well as Four Seasons, etc.
As for some others that have changed/closed/been renamed: Kuilima (now Turtle Bay) and Molokai Ranch (not exactly luxury, but novel and originally pricey).
