When I was going to university, there was a club taught by one of the professors that was completely free. I continued training, that I had started in grade school, and then taught for a year and a half. I think for college students it would be easy to find a place to train. They have access to all of the college facilities. Those that lose a job or have families that, rightfully so, take priority over training at a dojo have the most difficult time to find a suitable place. My two cents.
