I got the same type- my sister's name but my address- she was a minor, so I do all the booking anyways- they let me use it and she didn't go with me on the trip. I think what counts was the fact that we lived at the same address. Hope this helps. And ironically she is the one who gets all that stuff regularly- and I am the one who goes at least once a year- without her. It could also be because she now has a Disney VISA and I don't.
