First off which dorms are hill dorms? Secondly, do they take the bus to class?
Check out the map on Umich.edu. My D lives in MoJo and she mostly walk to classes if they are on main campus.
My son is in Couzens. He always walks to main campus (and football/hockey/basketball games, anywhere else). There is a bus stop right by Couzens too!!! He seems to think that you have to wait too long?? Oh well - it is good exercise for him.
D is in Lloyd Hall and walks every day.
Couzens, Alice Lloyd, Markley, Mojo and Stockwell are the Hill dorms. You do not need to take a bus from there to get to Central Campus but would need to take the bus to North Campus. It’s a 10-15 minute walk to the center of the diag from Markley.
Couzens and Markley are the furthest dorms from the Diag, and it’s still only about a 10 minute walk at a brisk pace, and about 15-17 minutes to the Union. A bus would be logical going to South Campus but otherwise walking isn’t a huge deal.
