In my opinion, it will be better if we choose City B.
We could see that there are a lot of venues that I think it have the biggest number of capacity as it’s listed as the biggest capacities than the other two, and people are not become bored. Furthermore, the people will be satisfied for the new airport and the transport there. Moreover, for the big capacities, the accommodation is quite better than the others. In addition, although the climate is cool with the 22 Celsius degree of temperature, the event will pass it gracefully. We will also try to trust the government for the security that he tried to controlled. So, from the event we could start to calm down the crime and war.
