Want to get the most of your Disney vacation? Get out of bed and get to the parks! Very few people will get up early on their vacation, so get up, get going, and beat the crowds.
The one exception to this rule is the Disney morning Extra Magic Hours park. The park with the Extra Magic Hours in the morning will be the busiest of the four Disney theme parks, that day. Instead, pick the park with the evening/night Extra Magic Hours and start at that park, early.
