In general, power chairs are treated the same as manuals wheelchairs. They have the same general ‘footprint’ and turning ability. There are some exceptions, but generally those are related to weight (less than 700 pounds combined chair + driver) or size (ie. chair with leg rests extended).
ECVs don’t have the same footprint and can’t turn as sharply to fit into smaller spaces.
DAS was used during the Guardians of the Galaxy Annual Pass and DVC previews. They were not using the
Lightning Lane for that preview, so did use it for DAS. If TRON is using the LL for the preview entrance/wait, I don‘t think they would offer DAS. At least right now, the wait has been quite short for most of the preview reports I’ve seen.
