If you want to come to do something or learn the culture I would checkout the Polynesian Cultural Center. There was little of what I saw online as far as that goes. One guy was doing weaving at the entrance and there was a display by the waterfall about instruments (which had a piece of bamboo for $45 if you are so inclined). The hawaiian games area was not staffed and no games were available to play.
Pretty much everyone was there to swim at the waterfall which is great but if all you did was take the $6 tram to the waterfall and back you would be missing out on a great collection of fauna.
