I would agree with most of what has been said except for one item. Obviously, this is just a personal opinion, but I do not recommend the Polynesian Cultural Center. It seemed terribly overpriced, the food was mediocre at best, the booths and demonstrations were something you might find at a local crafts exhibit, and the show (for me at least) was really boring.
Again, just my personal views - my experience talking with others is that about half of the people agree with MarySunshine and half with me.
