I started packing a week ahead of time because I was so excited. Also, because I have 4 kids. (Read about my packing methods here).
One good thing about our move is that we are now within reasonable driving distance to Disney World! I consider 7 hours reasonable... I know that's too much for some families, but when you consider the low cost of gas right now vs. plane tickets for 5+ people, it was WELL WORTH the drive.
Our kids are happier travelers in the mornings so we left very early. We were pulling out of the driveway at 4:12 am.
