A little pricey but worth it as long as you take your time to look through all the exhibits. I would maybe even go back through to make sure you see all of it because its over before you even realize it. It looks a lot larger than it is. The jellyfish wall is amazing - the changing colours really add to the whole exhibit. If you want to avoid crowds go on a weekday, I went on a Saturday which was a huge mistake because it was crazy busy.
