Heh heh, no. There is and there will be no "turntable."
The hallway was previously called "Full of Fear." It was essentially a chicken exit. A nicely themed and narrow hallway. Now, the walls have been knocked out, and expanded on the jog side (the dark area where all the buggies come from).
The hallway is now split in half. One side is going to still be the chicken exit (Full of Fear), and the other side is a queueing/bypass area for wheelchairs. The wheelchair parties are approached after stretch and asked a few questions. If they can make it up to load no problem, then they leave their chairs/ECVs in the hallway and a Maid/Butler takes it to the exit. If they cannot, then a Maid/Butler takes them through the hallway to the unload area of the ride, where they board.
It was expanded and the doors were knocked out in order to accomodate and exit point for wheelchairs after wheelchairs and ECVs started coming through the stretch rooms a few weeks ago.
One side of the hallway will be "indoor" Mansion themed, the other similar to the exit hallway/Crypt theme.
