My wife and I decided on our last night in Waikiki to do the sunset cruise. It featured an open bar (I think they charge $3 a drink on their earlier cruises), including their "Rigger Cocktail" which goes down pretty easy. The crew was great, and the view of Waikiki from the Catamaran after the sun had set was awesome. The only thing we never really had was the sunset as it was fairly overcast. If you happen to have a beautiful sunny day and are looking for something to do, you should definitely check this out.
