During the night, 8th to 9th of September.

"If you have to travel alone, travel in style."

Sleeper means a bus with beds. How grandeur!

They give you a bag to put your shoes-that you have to take off as soon as you step onto the bus, quite rightly as well-into, then you proceed to your bed on which there is a blanket and a Pokemon pillow and a TV in front of you (if you're lucky).
I am astonished, and for some reason also very proud.
