Our stay in Hanoi was extremely brief (had I known that there were some optional tours available for those who arrived earlier the first day, I may have arranged my arrival differently), and our next stop would be the train station where we would be boarding a sleeper train for Hue. It was strongly encouraged that we purchase sleep sheets as the linens provided on the train were not known for being hygenic. Our guide showed us where in Hanoi's market we might be able to find some and we were set loose to bargain our way to a good deal.
