In regards to the HHN / indoor queue comparison: For an indoor or outdoor queue you move forward based on when each party ahead moves, then just stand on the designated marker, repeat. How can they possibly maintain spacing in a house? Presumably, they will still be dark and ppl rush forward when scared, not really seeing the how close the next party is.. Which inevitably causes people to bunch up, how can they maintain social distancing in that situation? The pause between parties would have to be really long, which would cause longer lines, and when you consider the spacing need in the queue... just how? how they will they have the room to space that out? Cant do switch back lines without barriers, right? I dont envy the people in charge of the logistics that's for sure.
i'm not looking to shoot down HHN happening, I just dont think its truly the same as an indoor queue based on the constant movement.
