4. Conquer The Magic Kingdom Mountains.
No kids in your travel party means no need to pass people off through the rider swap system, or explore the height requirements of larger rides. This convenience means that conquering all The Magic Kingdom mountains is a must do. With no kids to complain about wait times, no fast passes that must be allocated for storybook rides and no one to chicken out and exit the ride at the loading area, the mountain trifecta will be more fun than ever.
