A clean first-time Vietnam structure for agents who need variety, cost control, and a route that can actually run.
For U.S. and Canadian groups especially, 10 days is long enough to make Vietnam feel varied, but short enough to control vacation time, budget, and fatigue. The mistake is trying to make 10 days behave like 14.
Fewer hotel changes and fewer optional extensions keep the proposal easier to explain.
The group gets major contrasts without constant packing, airports, and long coach days.
Hanoi, Halong/Lan Ha, Central Vietnam, HCMC, and a light Mekong layer can create a coherent sales story.

This is not a fixed tour. It is a clean commercial structure for agents to adapt.
Ten days works only if the route has discipline.
If the group also wants Cambodia, Sapa, deep Mekong, or multiple beach nights, 10 days becomes too thin.
Every flight day creates check-out, luggage, airport, transfer, and meal friction.
Long-haul groups remember arrival stress and departure mess more than one extra attraction.
Send the market, dates, group size, budget level, and must-see places. We can suggest what belongs in the 10-day version and what should be cut.
