I grew up with a clean-freak mom who always brought disinfecting Lysol to hotels during family vacations. I used to poke fun at her germ obsession, but now I realize that was a smart move . . . a really smart move. You know the obvious: the same hotel rooms are used by many different people. But you might not know that hotel cleaning practices are not always up to par, and there can be some seriously nasty stuff lurking in the room you're sleeping in. Of course, this is not an all-inclusive assumption — there are undoubtedly many hotel maids who do their jobs well and clean everything the way it's supposed to be cleaned. But there are exceptions, and there are hidden cameras to prove it. Just to be safe, these are five things you should always avoid when traveling and staying in a hotel room, or make sure to disinfect them or bring your own.
