This is probably one of the worst place you could go in the world. The whole mountain is built as a tourist trap but this is the worst.
They charge you 150¥ in low season for a plank (they call it a bed but there is no mattress and only one sheet) in a 12 poeple dorm, with no shower, no bathroom (you use the park's public bathroom), no heating system nor ventilation. They know you are stuck at the summit and they exploit it !
The only thing you can do to win on your side is sharing a single dorm bed with someone, it makes them angry but they can't do nothing against it ! More
