If you sick easily to motion, will you get sick walking through it?

The tunnel going in would probably cause motion sickness if you're susceptible to it but they have another way to go in if you need it.

Easily

The tunnel going in

The double doors on your left will take you inside instead of going through the inversion tunnel on your right

Yes through the tunnel

Yes you will. I just held on to the hand rales and closed my eyes to walk through it, it's not a long tunnel. Or they have a door for you to bypass the tunnel, you won't miss seeing anything if you use it.

Yes.

There is a sign to the left of the entrance of the "inversion tunnel" that will allow you to bypass it.
