There are many reasons that affect the choice of a host city to hold an event: infrastructure, socio-political situation of the country, international relations at a global level, etc. But what happens when, a few days or months before the celebration of these events, the venue is changed? This is something that happens constantly for very different circumstances: social crises in the host country, financial crises that make it impossible to meet the investment required for an event of this nature, natural disasters, epidemics or pandemics, and so on and so forth.
