For a first mixed-age trip, keep the option the whole car can complete more smoothly

With seniors and children, destination choice is not only about reputation.

It is also about which option asks less from timing, tolerance and constant adjustment across the whole group.

Sailimu Lake usually works better as one clearly defined scenic day

Its strength often lies in clarity: the family can understand the day's purpose and support one main scenic goal together.

That cleaner structure matters on first trips because it reduces friction and negotiation during the day.

The Duku Highway is more of a road-experience choice

The Duku Highway is valuable, but it asks the family to accept the road itself as a major part of the experience.

That usually fits better when the group already knows it enjoys that style and can tolerate more route dependence.

Choose Duku first only when the family clearly wants the journey-through-road feeling

If the group is genuinely excited by the road itself, the changing sections and the moving experience, Duku can absolutely be the better fit.

But that is usually a deliberate preference, not the safest default for a first mixed-age Xinjiang trip.
