(Just for reference: north is Men in Black, south is Islands, east is Citywalk and west is the backstage/creative area)
Basically, A would go through courtyard (same as Ghostbusters), but then go by the west side of 22, and into the south end of 23.
B would basically be the Yeti queue, but instead of going into 24, goes into the north end of 23.
A and B would exit right by the queue for A.
C would be unchanged.
D would follow the queue for Stranger Things 2, but then snake around the entrance to C with a break in the line for actors to egress.
C and D would exit same as last year.
(I could be wrong, but that's just how I think it'll go.)
