You mean the night before we arrive at WDW, right? Here's my history...
If driving, we're in Kingsland, GA. I will visit at LEAST three drive-thru windows to get everyone their favorites. We have dinner and our traditional Dairy Queen. Kids swim. We all go to bed early, because we are getting up around 4:00 - 4:30 to shower and stuff. We then drive straight to a park for rope drop. Woo-Hoo!!
If flying, I'll be packing the night before and calling my sister, asking where she is, why isn't she here, she was supposed to come sleep at my house so she wouldn't oversleep and cause us all to miss the plane. But she can't come, because even though I told her 10,000 times in the previous three weeks (and she said, "Oh, my GOD! Will you STOP?! I'm going to do it!"), she didn't get caught up on her laundry and is still washing. Finally, I'll remind her to be ready by 7:00, because I don't want to wait for her to take the hell dog out or whatnot. She will promise to have herself, the boys and the luggage outside by 7:00.
Then I will set my alarm so I can be at her house by 6:00, because I know she will oversleep if I don't go wake her up.
