Having a summer and winter games in 22 could be quite the unifying force and give both events more attention than normal. But I would be very sad for those athletes who qualified this year but won’t in 22. Two years is a lifetime for an athlete.
I have to assume that skaters and coaches will not be allowed to sit in the stands like they normally do outside their own competition. And probably no autograph sessions in the concourse between breaks.
Most people can't go to a Worlds anywhere in the globe. They usually attend one that's relatively close to their home (and theoretically more affordable). As a Canadian, I would be hardpressed to buy tickets to another Canadian Worlds if they don't offer refunds in this instance.
