PITTSBURGH — (WPXI) – A group of parents of children with disabilities, as well as adults with disabilities themselves, have filed a lawsuit against the owners of Kennywood, Sandcastle, and Idlewild over the company’s mask policy. Palace Entertainment, the company that owns the parks, has a policy that requires all guests to wear masks to enter the parks and while they are inside the parks. The policy does not provide an exception for people who have disabilities or can’t wear a mask for medical reasons. The lawsuit claims the company’s policy violates a part of the Americans with Disabilities Act. The lawsuit is filed on behalf of three kids with autism and their parents. The parents say their kids cannot wear masks due to their medical conditions. An adult with a medical excuse is also part of the lawsuit.
