You can request it via mail on the discard site, or when you are down there, you need to go to the customer service information booth (I forget what the official name is) only at Downtown Disney and they will give you a blank card, call the number on the card and they will activate it. Worked great for the days that I was down there. Be aware, that the credits on the card are only valid for 1 year, so only put on the points you plan to use.
