Harry Covair: As of Summer 2013 the Hilton Hawaiian Village has two firework shows: Tuesdays at 2000 hrs and Fridays at 1945 hrs. Pull up a chair and enjoy the show from Magic Island.
Kris Williams: When headed to the lagoon, take a right and walk to the end of the path. Then take the smaller walkway down to a "secret" beach. Perfect spot to watch the sunset.
