Sorry I'm late. 2 different accommodations.
1 is a pass you get added to your account at the front of the attraction to come back later and use the LL. These are supposed to be incredibly rare and not given out willy nilly. You have to get them at the attraction and itll let you comeback once you waited the same as thecurrebt wait publushedwgen you got it. I think this AQR(the acronyms confuse me
, so i might have these reversed). It's essentially an in person DAS pass for that specific ride. CM'S aren't obligated to give it to you just cause you ask. It's supposed to be a last resort thing. But it'll probably depend on the CM. It's not an advertised solution and if you walk up asking for it, itll pribably be less likely given. Though Disney knows which CM gives out each AQR, so theoretically there shouldn't be much abuse of these.
RTQ is the split the party accommodation where all but 2-3 members of the party(usually 2, 1 caregiver with the person who needs to be accommodated) can wait outside the ride while the rest of the party goes through standby. The party of the party that is in standby will be instructed to call the part of their party that is outside once they reach the merge CM(or reach the load area, depending on the ride), then they will wait in that area while the ppl who were outside then wait in the LL. They will wait in the LL until they reach their party who is waiting. They then join together and finish the wait together.
The second accommodation has seen fairly heavy use in my anecdotal experience, and seems to be getting smoother by the day.
