Hi I will be in Vietnam in November this year. My itinerary right now looks something like Hanoi (3N) - Halong Bay Cruise (1N) - Sapa (2N) - Ninh Binh (3N) - Ha Giang (3N) - Ho Chi Minh City (3N). I am confused between opting for multi-day tours to Sapa/Ninh Binh etc. and travelling there independently and then taking day trips from there. I am a person who likes to explore on his own. However, I want to know which option is better in terms of the trade-off between cost and convenience.
