You can also make your own door magnets, there are plenty of
DCL pictures and Mickey pictures on the internet.
What I did on our past cruises was I downloaded pictures I liked, did a text insert for names onto the picture and had the pictures printed at the photo shop at Costco for what ever size you want and then got some magnetic tape from a craft store, a peel off sticker on one side to attach your picture to and magnetic on the other side, walla done !
