SIF, aka Stuff In Face, I assume in a limited capacity. Just guessing, but something like the curtains and stuff should be fine since everybody is touching everything in the park anyway. But I personally wouldn't expect fishing line, rags, etc. I don't expect the "hard to see stuff" that could catch you in the face with your mouth open, but the obvious stuff you have to brush aside to enter the next room seems likely.
God forbid stuff takes a turn for the worse, not too hard to remove it. But feel like they need something to "hide" the next room.
