Move the students out of 117 and allow them to buy at the same reduced rates but until the premium seats sell out, give the students the option to upgrade to 117 reserved seats for a premium fee. They would still be able to get the $115 (or what ever they cost now) seats but could get back into section 117 for say an extra $100. You only sell what is left after full price premium seats are sold. Either way, you juice the income even if it is only by $100 per seat plus what ever premium seats you sell to alumni/non student fans.
