I think his point is that there is an advantage over everyone else in the sense that a non-DAS person has to actually wait in the lets say 50min line for the ride, go on the ride, then go back into the 50min line to wait in order to ride again. Thats 1hour and 40min of waiting in line, to go on the ride twice. If you are a DAS holder, you get your return time, and then for the first 50 min, you can go grab something to eat, you can go shopping, you could go ride a ride that has no wait time, and then report back for your first ride. Then you can make the decision to re-ride the ride, and for the next 50 minutes find another ride with no wait time, go grab a spring roll, or go grab some pins. For the person without DAS to ride a ride twice your taking that 1hour and 40 minutes out of your day and dedicating it to that re-ride. Whereas for the DAS holder, you can do the same double ride, while still having the ability to do a lot of other things in the park.
