Bus left from Cat Ba with 30min late, + some late because of the many stops we had on the road to take some people. We arrived with a total of one hour and half late but the driver was good and the staff nice, giving us bottle of water and a snack !
We got on one bus then had to get off to get a small boat then another sleeper bus. Took very long and was unorganised. The air conditioner was leaking drops of water on the sleeper bud. Got water and bread on the bus and made one stop. It was fine for a short journey but could have been smoother.
