There is a long line to go in, there is no charge, but they will ask you to donate when you are in line to get the tickets, which is ridiculous. Some exhibits are good, but some like North American Indians are disappointing. There are many seats to enjoy the exhibition, and there are many restrooms. It closes at five o'clock in the afternoon, and they will rush you out immediately. So my advice is to go early and make sure that you have time to wander around instead of being too rushed.
