I can't understand why hotels cannot provide simple idiotproof alarm clocks in rooms. It should be simple, quick, and obvious to set the alarm and to fix the time. Yet some clocks require a staff member to open the case to change the time and others have the frustrating feature of returning the alarm to either 6:00 or 12:00 after it has been used, so that you must re-set it every night during your stay instead of selecting the time once and just flicking the on/off button daily.
