It's the former Kauai Coconut Beach Resort. I never stayed there. But, a few years ago, I saw the luau there (good show, with emphasis on traditional hula, not tourist glitz) and I walked around the lobby and grounds (good location, but dated and unattractive).

See the reviews at http://www.tripadvisor.com/Hotel_Rev...ai_Hawaii.html

As I read the TripAdvisor reviews, it seems that the place had become dump, but that the new owners are doing a great job with the renovation. However, I assume there's a reason why it's a Courtyard, and not one of the higher end Marriott brands, so I wouldn't expect a luxury resort. But it seems like a good choice now, if the price is right.
