YOu'll be given a voucher type peice of paper. On one end it will have some little pull of tabs. One for Aladdin, one for Muppets and one for the other show (the name escapes me- the one with the Disney channel characters). You can see each show one time with priority seating. They let a limited number of people in to the show a bit before the rest of the guests. You'll get your choice of seats with out fighting the crowd.
For Aladdn you'll wait in a special line, and they'll let you sit where you want. For Muppets they have an area of prime seats roped off. Not sure about the other show because we never make it to see that one.
