Temp handicapped parking at Trail of Lights?

I’m driving my son’s friend and his handicapped sister to the TOL. She is in a wheelchair but has no placard (they do not own a car or means of transport).

To get a placard would take too long and require access to her doctors, etc, but she really needs to be parked close by and can’t traverse the regular lot.

Do you think there are parking attendants who would help us? Ot is there a decent drop off space close to the entrance or on a paved road that would give us enough time to pull over, get her chair from my the back of my hatchback, get it assembled, and get her out of the car and into it (and the reverse afterwards, I suppose) so I can park elsewhere?

Thanks for any assistance or ideas. I’m just trying to get them to a fun event they otherwise wouldn’t be able to see.
