When we waltz into a hotel room--be it a $30 bungalow in Thailand or a $3000 villa in Switzerland--we assume the space is going to be squeaky clean. A room that's spic and span is a basic, rightful expectation. Sadly, many fail to measure up. Between a revolving door of check-ins and time-crunched cleans, no room is impervious to germs. As a result, many hotel chains like Best Western have started programs using ultraviolet wands to sterilize high-touch items, even going so far as placing signs on top of remote controls indicating they've been sanitized.
