Walt Disney World this week made a change, increasing how long a DAS is valid for if approved. Up from the original 120 days, DAS is now valid for one full year. So guests will not have to reapply again until a year has passed since their last approval.
DAS is valid for the length of the ticket or up to 1 year, whichever is shorter. Once the service has elapsed, Guests need to re-register for the program.
