I travel frequently while working on a job, my old travel humidifier kicked the bucket. After much internet searching, I found this nifty little device. First off, it's MUCH smaller than you think-- slightly larger than a large box of 250-ct matches. Insert a water bottle, plug it in & you're set. Easy to clean & carry with you, the thing I love most about it is that if it runs out of water, it stops on it's own. It puts out a large amount of cold humid air for it's stature, but unfortunately it struggled against the incredibly dry air in the Minneapolis hotel room where I was staying. My recommendation would be to run the humidifier all day while you're gone with the door closed to your room and see if that humidifies the space more effectively.
