We left Hanoi for the final time on a Thursday night, cozily tucked in to the back of a sleeper bus. Our main mode of transportation throughout all of Vietnam were these buses. The first experience on a sleeper bus was to Sapa and it was not terrible, so we agreed to buy an “open bus” ticket for Vietnam. That meant we could travel between Hanoi and Ho Chi Minh City, with stops in Hue, Hoi An and Nha Trang, for $34 each. And we could stay in each stop for as long as we wanted.
