Monday and Tuesday I was at a huge conference, at a huge conference hotel. Lots of restrooms. Every restroom had lots of stalls (but only 1 accessible one).
This was a physics/optics sort of conference, which meant that the male:female ratio was about 60:1. Not much contention for the female facilities.
It seemed like every time I went into the women’s restroom there was exactly one woman in it, camped out in the accessible stall.
