I am allergic to the idea that local events are a major component in validating a destination, as if every trip were a festival hunt.
Disarm the hype: what's the point of an in-depth analysis of festivities if your goal is an essential business meeting or mandatory training?
What really changes tomorrow is the execution of the mission, not the color of local tulips.
For example, sending a cybersecurity specialist to a conference in The Hague is not dictated by a Christmas market, but by the necessity of updating skills.
