So you decided to stay in a Mountain Hut? I do hope you enjoyed your time sleeping next to お祖父さん＆お祖母さん.. It still amazes me how some had to of been more “fit” than I was!
The altitude adjustment made sleeping rather weird feeling.
I had ear-plugs and a night-mask, might be especially handy if you travel peak-season.
