I still say having cameras at the escape rooms isn't even good marketing. Because if you watch somebody complete the room, you have no incentive to try for yourself. You already know the answer, why pay money for the experience of struggling when you can watch somebody else struggle for free.
VS the Control Lab, where watching people get scared would likely entice more people to spend money to scare others. Signage out front of the mazes should be a thing though, saying that hey you're being watched and some scares are from this area, which would advertise it more, but also let people know that this is what's happening. If they chose to ignore it it'll be Fiends all over again, except most people still wouldn't know.
