I figure on the off-chance I can't get a room, I'll just use a sleeping bag.

Though we've only got ones for summer!

Won't you be cold in that?

We've got two, so I'll just layer them!

Then I'll wrap myself in cardboard, and I'll be all set!

Thank you, Yuru Camp knowledge!!

I've got a single room, but they allow two of us staying there.

By the cost of a semi-double room!
