In reply to Removed Userena sharples:
I've Done 24 hours on a reclining seat on a ferry ( in a storm)
in truth, I quickly found the floor preferable , though that might have been a lot to do with the rolling of the ship. In hindsight the cost for a cabin with a bed rather than the recliner, would have been worth the extra money.
So, of what you describe if you can't afford the bed on the train, a bed on a cramped bus sounds good, and possibly better than a recliner on the train. ( how long is the journey?)
