The ideal time is anywhere between 5 - 10 days. For a short stay, you can take up a Vietnam tour package for 3 days or a Vietnam itinerary for 4 days. If you have a few extra days at hand, you can go for a Vietnam itinerary for 5 days. If you can afford a longer vacation, go for a 9 days in Vietnam itinerary or a Vietnam itinerary for 10 days.
