Is it clean at this place because I know my friends kids all got noravirs. And got the hole family sick .

There are hand sanitation stations throughout

I would say it's really clean. When you get that many kids in one, place it's always good to have everyone wash their hands AND face as soon as you can afterward.

When I was there (very recently) it was clean and the employees there were constantly wiping down surfaces. So yes. It is clean
