I totally agree a crowbar is an excellent idea. I keep a 3' bar under my bed, a good flashlite, a knife and my wallet on the nightstand. You may need or want the wallet for ATM, credit cards, cash and ID for loads of reasons.

I would also make sure each person keeps a pair of sturdy shoes near the bed. If eyeglasses are needed I would add an old pair. I would also add a list of emergency numbers, relatives, coworkers, neighbors etc.

Depending on how you dress for sleep it may be a good idea to add a tee shirt and old pants or something.
