Hello po! Will be traveling sa vietnam for 7 days (excluding travel time to and from PH). Will be arriving in HCM and wants to go to Hanoi and Sapa. Question po:

1. How many days advisable mag stay each city?
2. Cost-efficient transpo from HCM to Hanoi and pabalik (flight to PH namin ay from HCM din). Kain oras po ba ang train and/or plane w/ security and checks na lines?

Thank u po
