I just missed a call from the Disney Disability Services, she did leave a message and this is what she said.
The only recent change to the DAS is that it is now added to your tickets electronically rather than being a physical card.
The kiosks are still there and you definitely go the the kiosks to get the return times put on to the DAS. You can still also go to either City Hall or the Chamber of Commerce to get a return time.
You are still able to use Fastpass in addition to the DAS return time, it is in fact recommended that you do.
You can have both a Fastpass and DAS return time at the same time.
You CANNOT have a DAS return time and a Wheelchair return time at the same time.
You do not get DAS return times at the attraction.
You do get Wheelchair return times at the attraction.
Hope that clears it up for everyone, it seems as though nothing has changed since we were last there in February.
