Is the $50 for freshman orientation for guests to stay overnight?

I know that I will be staying back, but if I pay an extra $50, does that mean my guest will be staying overnight also? Or can I just have my guest come with me on the first day and leave to come back the next morning?

@christinanguye My son didn’t register yet but he is planning to take his mom, me, and sister for $150 for the first day only.
