WWoHP day crowds on Halloween Horror Nights

[Disneyfied4]

Hello! Would like to tour Harry Potter during the day on a Halloween Horror Night. Will the crowds by heavier during the day b/c of the night party? We are looking at a Thursday day. TIA!

HHN doesn't affect IOA crowds too much since it's staged in the Studios and HHN is a hard ticket event starting in the evenings. IOA closes at 7pm during HHN but they might extend the hours a bit depending on the crowds for WWoHP.
