Comparing Housing Payment Plans

Just wondering the difference/benefits of Plan A-monthly, Plan B-Quarterly, Plan C-Full, and Plan G- Financial Aid Quarterly. Also, some of the payment options are broken down into initial payments, summer installments, and then monthly/quarterly installments so is the net price these all added together then? Are summer installments optional? For me, I have to take out loans to pay for housing, so does it even make a difference then which plan I have? Thanks!
