You may have already thought of this, and it doesn't solve the Snookums problem, but you could always grab your laptop/tablet and fuck off to the nearest library? Even the smallest ones usually have either a study room or at least a quiet nook at the back of the reference library where nobody ever checks. I've accidentally been locked inside libraries (public ones and school ones) doing this, and me and my friend who both didn't have a great deal of space for ourselves have used this method to unwind.
