A: It's perfectly acceptable—and quite frankly, necessary—to have extra outdoor rest rooms if you can't accommodate everyone indoors. Fortunately, you can rent models nowadays that are a big step up from those tiny one-door wonders you see at open-air concerts. These luxury loos have everything from mirrors and stainless steel sinks to air-conditioning and full-size porcelain toilets. Some even have stereos and artwork. To find plush potties in your area, type "luxury portable restrooms" into a search engine. You'll score a royal flush, indeed.
