How about for attractions where there are physical barriers to access? For me the
DAS isn't always about not waiting in the standby line. Some attractions have stairs, turnstiles, a large number of switchbacks, areas that are too crowded, in the standby line, even when empty that are physical issues for me getting though the standby line.
Do they just send you through the alternate entrance at these attractions (think Splash Mountain, Haunted Mansion, Space Mountain, Monsters Inc., Philharmagic, Finding Nemo, etc.) without a wait or how are these handled?
