Don't expect any type of alternate pathway and/or "ending".... It would take away from the experience, waste the limited space they already don't have, make the already long lines longer, and I believe Murdy already addressed the concept of alternate routes when someone asked him... I'm too lazy to pull up the tweet..
Honestly, if they wanted to be innovative & create a cool experience, as well as a great effect... since Heaven is all white, with a simple change in lighting/audio effects (possibly even scrims), that scene could change into Hell... and then back again. It wouldn't need to be complicated either. If executed right, it would still give you the "alternate ending" without having to have a split pathway. I'm sure some haunt has done something similar (maybe even Orlando)..
not going to lie... I kinda loved the announcement video. It was awesome.
