Looking for more info about the College of Design commencement

Has anyone attended the College of Design commencement before, grad or audience member?

I am curious about the details of it. Is there a rehearsal for grads? Do they call your name and you walk the stage shaking everyone’s hands? How early should family members arrive if they will be parking (accessible)? Can you leave after they call your name?

I can’t find any of these details online and would love to know more about it so I and my family can best prepare for it. Thank you :))
