Plan to have 4-5hrs to make the most of your visit. There are 5 different buildings each w a different focus of transportation (aviation, space, train, cars, water,...). You will find lots of relevant information and interactive activities.
There is a chocolate exhibit about the history of Swiss chocolate that is worth the extra cost and 20min. We didn't visit the planetarium but it had good program.
Food court and snack bars available.
Good for little, big, bigger and biggest kids and grownups!
