I was able to secure on campus housing for next school year. However, recently one of my current roommates that I'll be rooming with again next year has been hard to live with. Won't go into why specifically.
I've been offered to live in a house off campus with a bunch of upperclassman friends.

What I'm wondering is is how difficult I'll make the whole situation if I decide to cancel my on campus housing next year. Will a random person be joining the room (would have been a large triple with me and my two current roommates). Can one of our other housemates take my spot in the triple and a random in the single?
