Route one: Hanoi and Ha Long
- Day 1: arrive in Hanoi and keep the first evening close to the hotel.
- Day 2: Hanoi heritage, neighbourhoods and food.
- Day 3: travel to Ha Long for a verified cruise format.
- Day 4: return to Hanoi with an open afternoon.
- Day 5: fly home with a protected airport buffer.
Route two: Da Nang and Hoi An
This is the lower-friction two-base route because Da Nang airport serves both places and Hoi An's Ancient Town is about a 50-minute drive from the airport according to official tourism guidance.
- Use Da Nang for the airport, beach and one structured excursion.
- Move once to Hoi An for the Ancient Town, food and a slower final night.
- Keep central Vietnam weather in the decision; late-year rain can affect river and coastal plans.
Route three: Ho Chi Minh City and the Mekong
Stay in one city hotel and use a full-day excursion for the Mekong or Cu Chi. This removes an additional airport and hotel change, but traffic makes daily pickup and airport buffers important.
Quick answers
Can I combine Hanoi, Hoi An and Ho Chi Minh City in five days?
It is technically possible but operationally weak for most first trips. Two domestic flight days would consume too much of the usable holiday and increase disruption exposure.
Which five-day route is easiest?
Da Nang plus Hoi An generally has the simplest two-base geometry. A Ho Chi Minh City single-base route can be even easier if the Mekong is handled as a day trip.
