I can't imagine spending so much money on a resort, unless you really like being around people or need to be catered to at all times. I went to Oahu/Kauai on my honeymoon and I definitely preferred Kauai because it had less people and was generally more peaceful. You can find some really nice places for under $200, especially if you plan out in advance far enough.
We stayed at this place on Kauai:

It's kind of cool because the owner is the son of an influential local who helped create some of the beaches on Kauai and was involved in the community in other ways.
The pictures are horrible and don't do it justice, so I included some of my own. But we were literally 15 feet from the ocean and about 30 feet from a small beach that I only ever saw at most three people on (it was usually deserted). Sitting on the deck looking out at the ocean was incredibly peaceful and relaxing. At night we slept in the main room with the windows open and the ocean breeze coming in and it was perfect.
I'd definitely recommend going to a Luau that is advocated by the Blue book. I really didn't think I'd end up liking it but it was pretty enjoyable. The one I went to was:
Luau Kalamaku - Hawaiian Package Part of my enjoyment may have been due to the alcohol, which was unlimited and actually pretty potent. The food, though, was surprisingly good, too (despite it not getting the best marks according to the Blue book). This one gets the best mark from the book for the actual show which was good.
My wife went on the heli ride and really enjoyed it (Jack Harter Charters on Kauai -- they offer a doorless version too).
