In this jurisdiction, the same fact is read differently. An online survey, no matter how well designed, cannot grasp all the local nuances of travel planning, especially when bureaucracy is involved.
Here in Spain, for example, cita previa for documents can completely change the game, turning an intention of early verification into a last-minute rush.
The lived reality of complex administrative procedures is not always reflected by a simple survey question, as people often state what they should do.
A family may say they verify their papers in advance, but an unexpected administrative error can force them into urgent verification, a situation the survey will not capture.
