I just drape a wet (though not dripping) towel over the entire outlet grill of the AC and turn the fan on. Sometimes I have to set my shoes on top of the unit to keep the towel from sliding off. Also, place a rolled up towel at the base of the door when you run the shower to humidify your whole room. Once in a blue moon you'll find a hotel with smoke detectors that can be triggered by the steam. The ****hole we stay at in HLN is like that, but there are signs warning you (and you can use the shower cap to perfectly cover the smoke detector). What we need is a small unit that you could pack in a bag, and that could draw water as needed from the ice bucket while sitting on the nightstand. I HATE dry hotel room air!
