Reserving Rooms at Rose Hill?? (the Dance Studio in particular)

Current student at Rose Hill. I'm a dancer and well, want to dance. I know there's a dance studio in the Keating Hall basement- I've been there once or twice to dance and choreograph when it seemed to be empty- though every now and then someone would walk in and say "my bad!" Wondering if there's a formal (or informal) procedure to book rooms on campus as a student, especially now that the academic semester hasn't begun yet and clubs aren't booking rooms left and right.
