It's huge! You really need a whole day if you want to see/ experience it all. We were a bit late (unfortunately) because we wanted to see it all but couldn't. The museum part with trains was so nice to see, we also enjoyed the moon landing show in the planetarium and did go on the Swiss Chocolate Adventure (nomnom)!
So please, if you want to visit it all: go early in the morning :)
