Only if you want to participate. No need to do so and the kids are well supervised. You're not expected to "participate". Sit back, enjoy and watch the kids go wild.
You don't have to crawl as there are many other places to explore. However many places do require you to be fairly nimble in order to get to it.
There are tunnels, but you do not need to crawl through them to get around the museum. There are stairs and elevators. The tunnels and slides are just a more interesting way to get around.
No, you do not have crawl. As an grandfather, my fun was watching my Grandson do the things kids do at this place - have fun, and this is a great place for that.
You don't need to crawl through tunnels. It is fun for the kids though.
An adult is required for the kids to enter the caves and you'll lose site of them quickly of you don't follow them
There is a lot of crawling in the place, but you are not required to do it. But, you will have a hard time keeping track of the little ones if you do not crawl with them. You will lose sight of them easily.
You don't have to. There are areas you can walk through the tunnels and keep an eye on the children.
For lots of it yes, but there are also plenty of place where you dont have to
