I know HHN is many people's escape from reality as it my group's, but thinking about how masks or Plexi/shower curtains might interfere with your enjoyment of the event is ridiculous.
Yes, you might only be in any section of the the house for 15sec and all evidence indicates you should be fine...but the scareactors are stuck in that area (I believe) for 45min shift.
GET OVER IT!!!! Would I prefer no masks or Plexi? Of course. But the workers have lives and families too. Does Plexi stop Covid? It's debatable, but if you have a sheet of it in front of you, can water droplets make it your way? No. Science, on both sides of the isle, proves that.
The job of a themepark is to entertain you...but NOT at the risk of their employees, or your, health. Any restrictions implemented are not to screw over your enjoyment...but to protect everybody. They want you to have the best time ever and post your reviews on social media.
Will wearing boots protect you from rattlesnake bites? Not always. Is walking through snake infested areas in flipflops vs boots dangerous? Yes. It's a best practice to keep guests and employees safe...not a guaranteed success or most enjoyable situation, but better than the alternative. Half-assed protection is better than no protection.
Sorry, end of rant.
