Another indirect cost to consider is storage cost. Is there somewhere on campus where students can store belongings over the summer? If not, and if the school isn’t within driving distance (or, as in our case, we simply didn’t want to haul all D’s things home and back again), the student will need to rent a storage unit over the summer. At the suggestion of another poster, I hired movers (cost $75) to move D’s things into storage. It was cheaper and more convenient than me making the trip (which would’ve included hotel) up and back to help D move her things.
