In terms of climate conditions, hasn't Qatar guaranteed that there will be some kind of super stadiums with fully air-conditioned throughout the stadium? I think I've heard something similar.
I know that the Qataris are swimming in wads of money after the LNG prices went up by 20x during recent times. But at the same time, the players might find themselves in unfamiliar territory with a lot of restrictions. They can't go out with their friends to have a couple of beers. They can't even bring their girlfriends to the tournament, because unmarried couples are not allowed in Qatar. And more importantly, although the stadiums may be air-conditioned, we can't expect the players to stay there for 100% of the time.
