I would run this by with the management not just the front desk staff. The hotel would be happy to leave your room empty and bill you for it if you demand they do so... maybe leave some disposable toiletries and a cheap shirt of two as window-dressing.
I've done that before for short trips back and forth and kept the room for a couple of days while I was some where else but two weeks would be pushing it.
