Enough theory, what matters is what we can act on.
The impact of local events on travel planning is not a universal truth; it is a trigger that heavily depends on the actual goal of the traveler.
If your goal is to visit family during Eid, you do not change your destination because of rising ticket prices; you manage the additional cost as a fact.
The real question is always: what is the operational framework of this trip, and how does the local event fit into it, rather than invalidating the destination itself.
