Dear Ms.Nga,
Thank you for your attentive service. We are still waiting to confirm our flights to Vietnam in November and after that the exact schedule can be fixed.
Knowing that the trains arrive at 2:30 and 5:30 in the morning made us a bit hesitating about our initial plan, as it is not a very good time to check in a hotel or to go anywhere with luggage and tired body. We are seriously considering stay a night first at HCM City, or fly instead.
We do appreciate your speedy reply which we found very helpful and it does is impressive.
Thank you and regards,
Keith Chow
