I am seriously thinking about buying the cheapest adult-sized bike I can find and keep it in the back of the van. Then when I get to campus, I can just yank it out and ride it to my classes. I would arrive at class a little more relaxed and not huffing and puffing. I have 10 minutes between classes, and my longest walk takes about 15 minutes. Sometimes I get let out of the previous class late too. So it is possible I can be seven or eight minutes late!
