My son was chosen to do this and it was one of the highlights of his trip. He is a ham--actually, he really likes people and is very personable. It didn't hurt though that he had just had a Kidney transplant and had to wear a surgical mask all over Disney. At first we didn't think he had been chosen because they chose a much older guy--probably late teens/early 20's. But then they did choose DS and when he pulled that sword out, the look on his face was PRICELESS! I hope you have good luck. Try to be there early and get up front. If you're in the back, they may not see your DS. Best of luck to you and your son!!!!
