Packing at a moment's notice can add unneeded stress to a day. Having a semi-ready suitcase packed and ready is a good de-stresser. I would recommend it for anyone who travels frequently.
Throw in the basics. You can add a few extra clothes on your way out the door. Keep a toiletry bag in it or ready to throw in. I purchased and put a hairbrush in my suitcase after waking up to blow-dry my hair on the road without one, not once, but twice! A small but good investment in sanity!
What I was missing was my old travel hair dryer that had finally died on me. Compared to my normal folding hair dryer which takes up a quarter of my suitcase, this one was less than half that size. But it had died. Checking out the local store where I had originally bought it many years ago, it was not to be found.
Not to be deterred, I began my web search. Amazon.com proved faithful once again. The replacement has arrived, is powerful enough at 1,000 watts, and slides inconspicuously into my suitcase in its own small pouch.
