There’s a sweet spot on planning a Disney World vacation. If you under-plan, you’ll waste time and may find yourself confused and lost. However, if you try to plan every single moment of every single day, well, you’re going to be disappointed and frustrated. Things don’t always go the way you want! Rides break down, one park can be outrageously crowded, it can start raining, or your feet might just get tired of walking. You need to be able to go with the flow and have contingency plans. If you happen to pass a ride or show that looks like fun, just duck in!
