I think the best thing to do when you want to do a school visit (s) and have limited days - is handle things geographically.
So Lawrence is in Wisconsin…it’s a stand alone.
Wooster in E Ohio and Clark in Mass.
Those are sort of stand alones.
A Muhlenberg, Goucher, St. Johns, W&M, Elon could work - but W&M is highly unlikely based on what you describe.
It really depends on how many days you have to determine how many you can do.
But the three - Goucher, Muhlenberg, St. Johns - would be the most efficient route if you will.
If you did Clark, Marist might make a good fit given the student may be on the spectrum.
Good luck.
