I went to take a look on my own.
I didn't see anything interesting.
From previous posts, it seems that you need to have a LOT of time on your hands (or luck) to get a glimpse of something.
All I saw was dudes standing in the corners of the room waiting, and some sitting, using their phones to pass time.
There was maybe some noise coming form upstairs, but nothing was visible.
Are the downstairs peasants supposed to be able to see anything happenning upstairs ? Or do the upstairs couples only offer shows to each other ?
