Though this may add fuel to the fire, when I had hoped for the opposite effect, I just called 1-407-WDW-INFO.
I asked if there were family restrooms at the them parks. "Yes."
I asked how I could find them. "They are with the other rest rooms."
I asked if there was a difference between a family rest room and a companion rest room. "They are the same."
Now, I've gotten my share of misinformation from cast members before so I don't take this as WDW gospel. But the answers came very quickly - the CM didn't have to think about them at all. There were no lengthy consultations while I hummed along to hold music.....
MommytoMJM: "And to a PP, no, companion restrooms are not for anyone needing a companion. They are for those of us who may need help in a restroom by an opposite sex person for some reason."
So by your definition, is it appropriate for a dad & daughter or a mom & son to use them?
I guess what we really need are some one-holers - a child old enough to go by themselves but "too young" to use a public restroom alone could even go by themselves. My only concern in that case would be if the child locked him/herself in....
Shoot, maybe having our kids pee in the bushes or the parking lot makes sense after all....
