Speculation rooted on what was from the tours (
will be using video from Park Pass to bring the point home):
Looks like a core part of the exit element, will be on the left hand side as you enter the attraction plaza. Large lockers will be next to the exit area, with a water fountain area right next to the exits.
The thing that makes this interesting, is that I think this finally answers how the exit will be handled. Assuming guests will be leaving from this area (where ride photo purchases and return lockers will be), then guests who board on the side closer to Springfield will have to be climbing up a set of stairs to go back to the same side as the area near the maintenance bays.
Note with the stairs on this side that they lack the TM gate separator like how it is for the side near Cocina Mexicana.
As guests pass over the bridge in this area, the dispatch operator in the center will be enclosed with a rolling gate to block access from the GP to the staff members too, adding a layer of security while people pass.
As you walk on the bridge, you head down these stairs to rejoin the side of guests exiting near the maintenance barn, as you together head down to the Dual-Sided lockers facing those grabbing their kiosks back from the queue.
How this works in context to the queue before the fact of when you enter the station, I do not know--but I think we've finally been able to kind of crack the nut on how unloading is going to be for a part of the experience.
