Well, I'm the wife, but I'll chime in on behalf of the two obsessive planning dads who pointed me to the DIS a few years ago. They are the singular planners in their families, but I don't think they post here to say so when they're not in the midst of working on a trip.
One of those dads is the one who really showed me what "planning nut" means when he whipped out the color-coded spreadsheet complete with rides, meals, breaks, and backup plans. He didn't technically list out bathroom breaks, but I'm not sure whether he allowed them at all!
