I managed to put some relaxing tunes on and let myself lie there for another hour and the fire alarm finally went off at 5am when my wife's alarm went off. After I walked my wife out to her car, I stopped by the front desk and the manager was there with the fire suppression folks. Apparently a duct sensor had gone bad on our floor and they were having trouble overriding it. The manager offered me compensation without me even asking, so as of now I'm happy with the proposed resolution. Everyone was very apologetic, just not a fun way to spend the evening.
EDIT: Alarm just started going off again...
