My three ideas:
Could the hospital admit you the night before, given your situation?
Also, is there a motel nearby the hospital? At KUMC, there is one a block away which shuttles DBS patients back and forth. I would check at your hospital and see if there is a similar service or perhaps a volunteer group or person nearby to help you up in the morning.
In KC, there are PD support groups who would supply a volunteer and I'll bet there is in Indianapolis, too. That's another avenue to investigate!
Good luck and let us know what you find out!
