If we consider local events as a major component of destination validation, then we ignore that this influence is often secondary compared to more fundamental constraints for workers.
If our company imposes fixed leave dates, for example, for the annual August closure, then seeking events becomes a luxury, not a determinant factor.
If a colleague has school-aged children, then their vacations are dictated by the school calendar, not by the San Sebastián film festival.
The priority is availability and respecting family or professional obligations, not the event itself.
For most of us, the process of validating a destination is first constrained by real life, then by local events.
