I have heard of people doing it!! I love the idea!
So cute!! I agree that I would find someone who you trust that you know can take her for you, and be sure you don't have to worry since it IS your wedding day. And she will probably have to leave and go home before you do (during reception, etc)? So have someone willing to do that. If I get married in Jackson's lifetime, he will definitely be a part of it somehow!!
