There's something strange about that specific hotel (Sheraton Centre Toronto) .. I've only stayed there once, but the fire alarm went off TWICE while I was there .. A colleague of mine stayed there a year ago -- the fire alarm went off during his stay (his only stay) .. I was up in Toronto a couple of weeks ago and chose to stay at the Hilton across the street while a friend chose the Sheraton (free nights via points) --- the fire alarm went off at 4 in the morning ...
There is either way to many fires there, the fire alarms there are on the fritz, or it's just one hell of a coincidence .. =)
