How? For onsite guests, each guest must show their "Key to the Magic" card. This is just a fancy name for your room key, which you can also use to charge in-park purchases. It is given to each member of your party at check-in with the dates of your stay and that person's name. You also need a valid source of admission ticket for entrance. For guests staying offsite, you enter just like you would normally and the MM is deducted from your ticket. For all guests, there is no extra piece of paper or voucher needed for MM. That piece of paper that they give onsite visitors is just for information purposes. It, by itself, does not grant MM privileges, so you cannot pass it on to someone else. All you need is your ticket and if you are staying onsite, your room key.
