Before getting excited, one should always ask oneself: what is the exit condition if everything goes wrong, regardless of the local event?
The impact of local events, although real, can be entirely overshadowed by fundamental factors or unforeseen events.
If a region is affected by floods, as was the case in Wallonia, the presence of a festival becomes completely insignificant for the viability of the trip.
Risk planning must precede any consideration of entertainment, because a major problem renders all other data obsolete.
