You know, I totally forgot... get some flip-flops for walking in the bathroom/showering - hell even just for the carpet floors. It's really scary what's left behind by your hotel-roommates (that's what they are, and they just slept in your bed!). One time I found blood on the side of the tub (I was a traveler for years) and I've seen the Dateline type undercover investigation with the blacklights and such.
Anyway, the other thing I always used to do was keep clothes handy. I sleep in gymshorts, so normally it was just shoes and a shirt for emergencies, but in the winter, I always had my pants, socks, shirt and coat laid out for a quick getaway in case of a fire. And keep a spare blanket, coat and sleeping bag, and hand/foot warmers in your truck (you had a spare vehicle key in your laid out pants right?) so if there's an evac, you get to stay snuggly warm while everyone stands outside waiting in the snow.
