I will soon go to Vietnam, Hanoi by another following weeks. I have booked a ground trip over there around 5 days 4 nights. On the first day, i will reached Hanoi around 8am. Thus, i wish to go Halong Bay for day trip and the second day i will follow the trip to Sapa. Anyone can suggest the package given for Halong Bay day tour? I wish to go Halong Bay and Sapa for this round trip but definitely i wish not to miss the Halong Bay.
