I was the guest in room 153 on the night of 9/12/13. At 3:00 a.m., I was awakened from a sound sleep by the repeated beeping of a loud alarm. I turned on the lights and searched the room for an alarm clock, but could find none. Was the sound coming from the air conditioner? No. I kept searching, fearing the loud noise would awaken other guests. After about ten minutes of searching, I discovered that this loud alarm noise was in fact coming form the microwave oven in the room! I unplugged the microwave and the noise stopped. But now, of course, I cannot go back to sleep. And the date today is Friday, the 13th.
