Sorry if this has been discussed, but I am a little confused. I just purchased MM for our trip the first week of March. I was logged into MDE when I did. I chose the option of having it shipped. Will I get a card in the mail that I have to link or will it just show up in MDE? It isn't there yet and I tried to link it with my order confirmation number but that didn't work. Thanks so much for your help. I appreciate all of your help with my questions. This is only our second trip and I am trying to have everything prepared and to learn as much as I can!
