I was about 7 or 8 and we were in Adventureland in the Magic Kingdom, and my dad took me to the restroom. I was surprised that there were no urinals inside, but we both took care of our business and walked out without incident.
It was only after we exited that my mom told us that my dad had led us both into the women’s restroom.
French women are not shy. Several times when in France I have been using the urinals as women jump out of the long ladies queue to use the empty mens stalls.
