I think UMich is going to do everything possible to have the dorms open in the fall. If for no other reason, UMich is losing a ton of money with the dorms being closed and students not using meal plans.
For whatever it’s worth, my freshman son is having a great second semester so far (at least socially). Instead of living in the dorms, he is living in a big old house in AA with 6 other guys who pledged the same fraternity as him. It stinks not having in person classes. Hopefully, all professors will be vaccinated before the end of the summer and that will allow for in-person learning in the fall.
