Agreed. That is the rub. People with
DAS accommodations who go on ROTR can book it 3-10+ times per day, while also going on other rides. That is not equitable access, that is better access and is putting a strain on the system overall.
DL/WDW can even look at their own system in Tokyo Disney. People can leave the area, go to the bathroom, shop, etc but cannot double dip on waiting in one queue while simultaneously experiencing another.
"Please present the Park ticket used to register for the Disability Access Service to the Cast Member at the attraction or Disney Character greeting location.
Guests who have difficulty standing in line for a long period will be able to wait at a separate area, along with thier party, instead of in the queue until the designated time (you may not be able to experience the shows or presentations at the queue area).
You will not be able to experience another attraction or Disney Character greeting while using this service."
