The demand came in peaks, exactly as event demand does.
The window was not one long high season. Demand concentrated hard around match days, softened in the gaps between them, and rewarded calendars that priced the three phases — lead-up, match day, day-after — differently. Hosts who set one proud flat rate for the whole window watched the gaps sit empty while their match nights sold out at what turned out to be a discount.
That shape is not a World Cup phenomenon. It is what TIFF does, what Caribana does, what a playoff run does, at smaller amplitude. The tournament was simply a loud enough version of the pattern that owners who had never noticed it before couldn't miss it.
