I will be travelling from Hoi Ann to Ho chi Minh next April. I am not sure if you can fly direct between these 2 places or would it be worth going by train part of the way. I have read some reviews about the train journeys along the coast. I would like to experience a little of the train journey. Can you book the train ticket in Hanoi if I decide to travel from Hoi Ann to ? Nha Trang or Dalat by train? How long will the train journey take?
