Tip: Avoid Magic Kingdom on Mondays.

Do not visit the Magic Kingdom on a Monday. It is packed! For many people, Magic Kingdom is the first park they go to, which makes the days or day after most people arrive typically very crowded. Tuesdays, Wednesdays, and Thursdays are always better for the Magic Kingdom. Instead, visit one of the other three parks on Monday, as they will be much less crowded.
