Sign outside of Avatar Flight of PassageIf you need to leave a long line because nature calls you might not get your place back. The good news is that there are restrooms near the entrances to most of the popular rides. Check your park map or the My Disney Experience App for the locations. If you’re traveling with young kids, insist that they try, even if they claim they don’t have to go. Kids don’t understand just how long a 70 minute wait is, they live in the moment, so take them before you get in line. It’s better to be safe than to lose your place.
