Only Hilton's on Oahu are all in Waikiki.
As mentioned, there is Hilton Hawaiian Village, with 3 HGVC timeshares, and something like 3 or 4 hotel towers (including the famous Rainbow tower).
Also in Waikiki are the Hilton Waikiki, a Doubletree hotel, and on Waikiki Beach Walk an Embassy Suites, and Hokulani, which is a converted hotel into another Hilton timeshare. (not sure if that one is open yet though).
If you would be willing to try another island, I would recommend Hilton Waikoloa Village on the Big Island, about 20 miles north of Kona airport. Outside of Aulani, it's the most Disney-esque hotel in the islands. (in that it has trams and boats between the various buildings.)
If you would happen to have MarriottRewards points, the JWMarriott Ihilani hotel is right next to Aulani, and Marriott Ko Olina Beach Club (a Marriott timeshare) is just 2 lagoons down from Aulani.
