Is that really a thing though? Do international travellers automatically park themselves in their home pavilion?
I know I don't spend a heck of a lot of time in Canada. Mind you, there's not much to do there, but I'd still rather spend time in pavilions whose countries I have never visited.
Unless there's a ride in Brazil, which I cannot discern from the very vague concept drawings, why would the tour groups spend more time there than in the other pavilions? From my experience, they like rides, rides, and more rides. (And flashing my son in the Pop Century pool ... but that's another story.)
