1st, I would call Disney and verify your info. Then ask what you need to do. My understanding from reading some other posts is that this doesnt seem to be a problem. Just make sure to put some identifying tags on your luggage and ME has done a pretty good job of picking those out and getting them to you. As most that have used it say, be sure to have a change in clothes in your carry on bags just in case.
Good luck and Pixie Dust!
