If you're talking about Baby Swaping you can do that on any ride. Just tell the CM at the beginning of the ride that you want to baby swap. They let the first person go through the line and when he/she returns your other other is wither give a FP type ticket to use then if the ride has a FP or they tell you how to go through a back door and in the out door of the ride.
My wife and I have used it on 2 trips and it always works well.
