When I was in school our campus police provided a secured arms room for storing students' weapons. It seemed to work fine for many students.
I'd go visit them and ask to see their storage facility (how the guns are stored/treated, who has access, etc.) and find out what the actual procedure is in practice. It may be that their official policy is 24-hours advance notice, but it is much more likely that they merely say that's the MAXIMUM notice they need. And that if you walk in on a Friday afternoon and say, "I want to check out my gun," you'll be on your way in 5 minutes.
That being said, I'd plan to take one or two guns at the most, and not my most irreplaceable ones. Keep it simple, focus on your studies and get through your first year. By then, you'll likely have made friends and more amenable plans for housing for the rest of your time at college.
I'll also do a little talking to a brick wall (if you're anything like I was
): Your courses are your JOB, and it's nearly a 24/7 gig. If you're out playing with your guns, you're wasting the precious time and money you (and/or others) have invested in being able to buy more guns (and food, diapers, car insurance...etc.) for the future. A little shooting can be a welcome stress reliever, but hit your stress relievers sparingly.
All that to say, if you take your guns, and find out that at the end of a couple semesters you've only checked them out 3-4 times, you're probably doing ok. If the campus police check-out procedure has been a constant thorn in your side day to day and week to week, you probably need to adjust your proprieties.
