9. Understand you can't have the perfect vacation
Rides break. Bad weather happens. As much as we like to believe that Disney World is its own little bubble where everything is perfect, chaos can occur. To try to strife for the perfect vacation is a fool's errand. We try our best to minimize the chaos but sometimes things are out of our control. Once we learn that, we can learn to take these issues and roll with them. Bad weather? Ride some rides indoors or go have a meal at one of the hotels. A ride breaks down? Try a new ride you haven't tried before. Just know, everything can't be perfect.
