This place is BIG! If you want to see it all, make sure to plan for enough time. We saw two floor in something like three hours. I'm not going to comment on what we saw, because that is a matter of personal taste. some we liked, some we just thought was stupid, but that's just us. There is more than enough to see, and it is presented in a very clean, clear way. I think we paid something like USD 20,- but I also understand there are times when it is free. so do your research.
