Thanks for wanting to explore this Onix. On your points, the exact materials of which the wall is made is yours to chose. It obviously should be sturdy. And my preference, in line with yours, would indeed be for the girls to be quite unwilling to undergo the treatment they are subjected to. They will be most relieved if the girl next to them is tortured instead of them. Obviously, as the festival might attract a lot of men, it is likely that heir relief is shortlived.
