The family posted a video showing the adorable reaction on YouTube. The description reads: "My wife and I decided to completely surprise our kids with a trip to Disney World. We packed up the car, then woke the kids up and put them in the car."
It only takes a moment or so for their daughter to realize where they are going. She's excited, but her little brother starts bawling.
The story does have a happy ending. The family says the little boy ended up having a great time at Disney World and is asking to go back.
Disney is the parent company of KABC-TV.
