It's fun when you pissed someone with authority off and get on the sh!t list and the local guard kicks an inmate out of their bed and puts them on a floor (they call it a boat but it's just being on the floor) and gives you the bed (the guards can't get violent with you, but they know how to get someone else to). Not every inmate is going to beat you up, but when you are moved from place to place during the month or more transport takes one of the guys who get's kicked out to make room for you is guaranteed to fight over it.
The one you don't think of is that they won't unshackle you to use the bathroom (especially on con-air) so half the guy's backsides are covered in their own excrement because you need your hands to wipe. Good times, good times.
