The elevator and a staircase are in the current gift shop area (stairs wrap the elevator). Then, there used to be escalators that headed there that are to the immediate left of the current line queue or, if you walked straight in the doors without turning, you'd walk into them as they're that wall that's right there as you enter. If you go left at the attraction entrance and follow the path that leads to the gift shop, I believe you are walking around the escalators.
This is stretching my memory quite a bit, so I think that's right.
Here is a picture that shows the spiral staircase wrapping the elevator that are now in the gift shop (you cans see the current exit off to the right and what I believe is the original attraction unload to the left where two people are walking):
This isn't the best picture, but you can see the top of the escalator on the far side:
