They let you through the security checkpoints and through the turnstiles, but the hold everyone up outside the tunnels to go under the train-tracks. There isn't really a bad place to see this from, we saw it twice while we were there, and I have a very sweet picture of my DS and DD watching all the characters on the train in front of the "hidden mickey" flower bed. It's my favorite pic from our whole trip! This is one of the shows that gets me misty when we see it! A must see in my book. I'm still trying to find out how to be the family to throw the pixie dust.
