Seriously, hotels are gross. I've seen reports on other shows like Dateline and 20/20 about motels that never change their locks or the amounts of semen in any given hotel room; that's how it goes. This is small beans; I've never died from using hotel glasses and I question how wide-sweeping this problem is. The fact is, no matter where you go, the rooms are kind of nasty but probably not overtly threatening to your health.
I'm not running around boycotting Embassy Suites either; I've found that no matter name is on the marquee, hotels are pretty independent. Holiday Inn is a great example; I've been to world-class Holiday Inn's and I've been to Holiday Inn's with bugs and dirty carpets and Norman Bates at the front desk.
I just do the responsible thing; I read reviews on hotels before checking in. You can't base anything on a name or a price, just do 10 minutes of research and you'll save yourself a whole lot of grossness. We're lucky enough to live in the information age... why not use it? If more people actually researched the things they spent money on, maybe every business owner from small proprietors to corporate CEO's would finally consider making changes.
If you're a battery, you're either working or you're dead....
