Recently I learned that the Soyuz crew ship can take up to three days to reach ISS. I know that most of the time the travel takes only about 6 hours, but still:
In case something happens, you have to spend about 3 days in relatively small ship. It looks to me really small to do anything else than sit in your chair.
So, if you have to choose 3 day travel to ISS, how and where would you sleep?
