Worthwhile noting that most single hose AC units can usually be converted into double-hose with some cardboard, hose, and a lot of duct tape. It's worth doing too - you'll normally get almost the double the cooling effect from a double hose unit of the same wattage as a single hose one, just due to the fact you aren't wasting coolness out of the window. If you do this, note that it's important to use extra large and short (insulated) hoses, simply because the blower fans in your unit aren't designed for so many yards of hose.
