This would have been my advice as well; maybe spring break would work with your school schedules. In fact, even if you've already made the booking, it may be worth paying the fee to reinstate the miles so you can do this. As pointed out by others, that was almost enough miles to get you 2 off-peak tickets to Europe (with a possibility of throwing in a free one-way to Hawaii at a later date). It would cost you $175 (I believe) to get those miles reinstated but I would seriously consider it as it may be worth it.
