If we assume that local events are a major determining factor in choosing a destination, then we often overlook the practical constraints of travelers.
While cultural events can enrich a stay, they are only one consideration among others, often subordinate to imperative constraints.
For example, if a participant must absolutely attend the Mobile World Congress in Barcelona, then the dates of the congress take precedence over the local festivals, regardless of the impact on price or availability.
The budget allocated and leave availability are decision factors much more influential for most people.
Ignoring these realities leads to overestimating their role.
