First of all--there is no "handicap pass." There is a guest assistance card--but it will NOT get him front of the line privileges. It is a card that gives accommodations to meet the needs of the guest (such as using the stroller as wheelchair.) Most lines are mainstreamed, which means everyone goes in the "regular" line. The only people who sometimes go to the front are children on their "Make-a-wish" trip.
The card says right on it that it is not intended to make your wait shorter (as a matter of fact, it sometimes makes it longer!) Also, the maximum number of people included is 6--so will not accommodate their whole party.
