This is not my list, I found it a while ago when we were planning and just dug it back up for you in case you need it. No idea where I even found it now. The best I can remember, the orginal poster said it had been passed around a bit, so hopefully it's still accurate. It's a list of the family/companion bathrooms at Disney.
