You just go to the Fire Department or the shop by Sleepy Hollow. You walk up and they hand them to you. They'll scan your bands at the sensor they have right there. They'll ask if you've played before, and if your answer is no they'll explain it to you. There's no linking via phone or anything. When people above talk about linking, it's thru the magic band. Basically you get a set of cards for your party. You then run around the park to stations which have hidden gems that you wouldn't notice if you never played this. You're all linked together, so you can all trigger the mirrors. What we do is we'll divide up a few of ours... That way more of us get cards. They'll advise against this, because it'll generally mean splitting up your party to go to entirely different parts of the park. Also your bands will only activate YOUR missions, so if you are going to travel as a group, it's best to be all on one link so all your kids can go up and do it and not get the "you're in the wrong place" error screens.
