My fiancée and I have been to Disney World a total of 5 times since 2000 and it was really just last year that we started to take advantage of the Extra Magic Hours benefit offered to guests of Walt Disney World Resorts. What a difference going a bit early or staying a bit late makes in terms of waiting in lines! First of all, it’s much cooler than in the middle of the day when the sun is its warmest. Second of all, the waits for rides are cut in half!! There aren’t as many people around at these hours, especially at night, so a normal wait for Splash Mountain might take 2 hours, but at night you might only wait ten minutes. I understand that staying late might be difficult for families with young children, but if you can manage it, then I highly suggest you do it.
