We stayed 3 nights pre-cruise a few years ago. It's right next door to the Hale Koa (military hotel) and the general public can order drinks from the boardwalk bar. The HHV grounds are just gorgeous. My daughter was there for a Medical conference in February and her photos tell me they are still taking fabulous care of the grounds.
If you are looking to save a few $$, you can book it on your own for a little better price usually (try using AAA discounts, etc.).
Enjoy!
