I know this might sound a little odd but what about renting a room (Airbnb or VRBO) near SDSU according to your schedule. Maybe you stay overnight twice per week. You would be surprised how low the cost can be.
I use room rentals all the time and if you develop a relationship with the person, it could be a win-win. Especially if you did it ahead of time.
