Some random thoughts/analysis regarding the precinct...
1) Does anyone else think if there could be more than one entrance to the Wizard of Oz precinct? They could have a separate entrance/exit to and from Wild West Falls. This could give the entire park more of a feeling of flow and less of a feeling of dead ends in the park.
2) I wonder how faithful the precinct will be to the concept art. In the concept art, there appears to be a 'Kansas-y' barn behind the main green structure. Could it be that guests entering Oz will begin in 'Kansas' and walk through into the world of Oz? Or could that barn structure be part of the queue for the duelling coasters?
3) On that thought, where will the queues for the ride begin and end? In the concept art, it appears that the queues for the rides are coming out of some of the buildings? Could it be that there will be an indoor section of the precinct? What could that look like?
4) I also wonder if the coasters are the only attractions planned for the precinct or if there will be any flat rides. Maybe they could even have a themed Vekoma madhouse inside one of the buildings?
5) Just a random/silly aside. Initially I thought it was strange that Oz would be located next to Superman Escape, but it kind of makes sense in a weird way considering that Superman grew up in Kansas!
