How much is appropriate for Cambodia to travel with a group for 8 days?

this depends on whether your group includes self-funded projects.

The consumption level in Cambodia is still relatively low, and there is no other place to spend money except to participate in self-funded projects and buy some special products.

It is suggested that in addition to the expenses required for the self-funded project, each person should bring about another $3 to eat in the bar street and buy things in the old market, which is enough.
