I have never been asked to show my AP (Contemporary & Grand Floridian). But, when you do get it activated, DO NOT go to the Magic Kingdom to have it done! They have the longest lines, and we waited what seemed like forever to get it done! There was even a guy who refused to wait in line who stood at the exit until a window opened, and he went up to it. The CM told him that he had to wait in line, and he said that he would not; and it ended up that 3 CM's had to deal with him, until one of them finally gave in and did what he wanted. So, the guy held up the line (CM's weren't taking more people to help because they were dealing with him) and it ended up that everyone stood still in line for 15 minutes until a CM agreed to help him!
