When my 4 yr old "has to go" she gets in a panic and has to get there in a hurry (even if she just went 10 minutes ago). We will be there seven days around Easter. Since the parks are busy, I assume the restrooms will be busy too. Anyone been there during that time? I'll probably just have to break down a few times and ask if we can cut in line. It's either that or wet pants. I plan to carry a dry set of panties and pants with a zip lock bag.
Be sure to warn your child about the automatic toilets as well. My DD was scared to death at the age of 5 of the toilets and still insists I go in with her and "cover the eye" so I won't flush on her. It really scares a lot of kids. Just cover the "eye" because the toilets at WDW sound like they are flushing the whole world as well

Will also consider the Preg Moms as well, thanks!
