We did it and it is very easy. Have all your id with you. When you go through security, at the top of the escalator there is a round type desk area staffed with castmembers. They will have your documents, they will hi-light everything you need to complete. Have all your pertinent info with you. You complete everything, they doublecheck it and you go get in line to check in. It only takes a couple minutes because they make it so easy. I had ours all completed by the time hubby parked the car, that's how fast it goes.
