What everyone repeats, no one checks: a Google Forms survey, even with 78 responses, cannot explain the complexity of identity document verification behaviors.
The "vacation planning" is a lazy cliché that masks the real constraints.
Pre-emptive verification is often dictated by the administrative delays of passports and visas, not just by habit.
For example, in Belgium, the need for an appointment at the municipality for a new passport imposes a delay that forces anticipation, regardless of your vacation habits.
