The problem colleges will have is the same problem cruise ships (and sadly aircraft carriers) have - cram thousands of people together in tightly packed rooms where they constantly mingle with others in large groups for most activities including meals and … C19 will spread like wildfire. Not many of the college students will die, but a few will and more of the support staff from professors to janitors will. A PR nightmare.
My friends who are docs and nurses think that there will be a second wave of infections in the fall as distancing requirements relax and the weather cools off, similar to how flu starts to ramp up in late fall.
