I started out by hiding them in my dorm room. They rarely did inspections and I kept them in a corner of the room and shielded with a blanket + under the bed. So unless they were being especially nosey they wouldn't be found. That worked for about 18 months. Thankfully thankfully, the Biology dept did allow me to keep the snakes in a room in their dept after the doom evicted my animals... But I wouldn't count on your university doing that... I'd suggest working out that possibility first... Don't get caught in a bad situation, its not worth the risk to the animals.
It worked out for me but it could have easily been a VERY difficult situation.
