All indications are that
DAS will operate "normally" (ie, return time given) but an alternate entrance as opposed to returning to the now non-existent FP line. We had gotten DS up to waiting for 45 minutes easily so we were only planning on using DAS for a handful of attractions that either had MUCH longer waits or problematic queue areas (TSMM is too stimulating - he literally falls on the ground into a ball regardless of line length in that one). Now I'm wondering about the social distance lines and if that will be an issue. Yesterday he wore his mask for well over an hour outside in the heat with no complaints, so I think we are over that problem, but he has measurements in his head and was warning people "you are ONLY 4 feet away!" if they got too close.
On one hand,he will likely be the model guest for social distancing and will enforce it for everyone. They could probably hire him

On the other, if we are waiting in a socially distant line, it will get really annoying REALLY quickly for everyone around us if they need to listen to him lecture on exact distance for 30+ minutes in line.
Not sure how we will approach it.
