I think refunds of student fees and residence fees etc are going to be the least of our worries.I can almost...almost...see a case of them saying "well, if you live off campus you wouldn't get your rent back." Crappy argument since those chose to close the campus, but I could almost see it fly.
But the food service? The will not delivering that meal plan to my daughter, there will be no delivery of services. They should refund a portion of that, since we're only getting half a semester worth of services.
There must be kids all over the world in Halls of Residence too far away from home to get home and with casual jobs that may disappear, no money to get alternate accommodation if the Halls close.
Even then there's the issue of actually not being able to travel or even go back home if they are quarantined...or if their parents are quarantined.
How many of our 18+ kids have any clue about how to prevent cross infection inside their own home?
Lucky they mostly seem not to be getting too sick in that age group, but I'm going to worry myself sick anyway.
