Before rushing, it is important to understand that the impact of local events on destination choice is only a secondary consideration for most people.
The feasibility threshold of a trip is first determined by much more fundamental practical constraints, such as the available budget and imposed vacation dates.
If funding is lacking or the period is not free, the best event in the world won't change anything, because the exit condition is already met.
For example, wanting to go to the Ommegang Parade in Brussels makes no sense if children are in school and the wallet is empty, regardless of the atmosphere.
