It's great for dance parties! I've had Chris arrange a few, they're a blast. [there's actually a stereo system neatly fit into the walls, so the sound is very clean through the room, nice acoustics]

I have some fall mats, let me drag them out. [one wall had a closet, full of dance wear. As he's rummaging around, a suitcase actually falls beside him. He jolts out of the way, but a jumble of his past costumes scatter onto the floor. All of which Yuuri is sure to recognize]
