What are the critical things to see in an MSU tour

My DS23 will be visiting soon from OOS. He has been accepted, and is excited but wants to make sure the campus feel is right for him. What are the top things for him to see or do to get the best feel of campus and see if this will be his home for the next 4 years?

Try to schedule a group tour if possible. Alternatively, the school website has a self-guided tour with campus highlights that you can do on your own. Eat lunch in one of the dining halls. Call and try to schedule a visit with the department(s) for his areas of interest/major.
