While mask will be mandated at Cedar Point, i highly doubt it'll actually be enforced other than entering admission gates if that, for multiple reasons.
[*]They just don't have enough staffing (especially with no international workers) to enforce this policy
[*]It would cause a scene to kick a guest out not wearing a mask, possibly giving Cedar Fair bad publicly in an already heated season
[*]There are multiple circumstances (autism, asthma and other respiratory issues, kids having a fit) where a mask is inappropriate
[*]Cedar Fair probably has to have a mask policy for the state of Ohio to allow for reopening, but I don't really believe the park really cares for it.
[*]Mask are not a force field of protection and do not work like that, especially in a crowded environment like a theme park
While yes it's a policy Cedar Point has enacted, I doubt it'll cause much issue for guests that do not wear a mask, If you're in a crowded place like a theme park than you should accept all liability of any viruses that is out of anyone's control (Which COVID19 is not what we feared and way less scary than the media has made it out to be). Most policy's businesses have concerning COVID19 are security theatre and really only to get people out and into their business and permission to open, they don't really do much for protection.
