You go to Guest Relations in a park, say you need a DAS pass, they ask a couple of questions, then it’s added to your ticket/magic band for you and your party for the duration of your stay. So it’s an add on to your account, rather than a separate ticket.I actually got the impression you do all the DAS stuff before you arrive , save you precious time in a que & weed out any dodgy ones before they arrive, I can’t imagine it’s great to have that burden hanging over you of having to sort out your passes on day one x
Takes 10 mins tops, we usually sort it on our first morning
