A supper spreader is not really all that possible to stop. It's impossible to keep tabs on everyone who walks into the park while they're in and say you have a day with 10,000 people in the park, which is probably being generous at the start of operations. If even 1% of those are going around undetected willy nilly mask on and mask off, then you have about 100 people or so acting as super spreaders (and the people who don't properly use a mask are just as dangerous - it could get on their hands, they touch a railing, then who knows how many others get it, etc). And don't think all TMs are going to be super hygenic. Sure, on stage they'll be required to, but backstage? Backstage is when they'll want to rip that mask right off. I could easily see the virus running through TMs pretty fast.
