For child swap: you go through the queue as a family. Then when you get almost to the front of the line, one parent goes to the waiting room/child swap area room with the child, then the other parent goes on the ride with the other children. When the parent gets off the ride, he goes back to the child swap area which is near where he disembarked. Then he stays with the child and the other parent goes into the express line with the other kids and rides. So the other kids get to ride twice and no waiting in line again. The child swap area is a room with glass so you can watch the ride and has chairs and sometimes a tv. All the rides have them.
