Disney Free on Birthday?

Did you know that your child can get into Disney free on their birthday if you're planning orlando vacations anytime soon? I didn't know this but a friend of ours just said they were taking their child there on their birthday because of that. I looked it up and it's true. The Disney site says if you register the birthday during 2009, admission is free to one of the theme parks. If you're thinking of going to Orlando and you can arrange it around a child's birthday, sounds like a great birthday present to me!
