I made a video YEARS ago giving a warning about the cleanliness of your hotel room and how to clean it yourself BEFORE using it. (video attached beneath this one.) But I NEVER even imagined this! You have GOT to watch this video!
When travelling it's best not to be cheap. Keep in mind that when you choose to sleep in a hotel you are sleeping in a bed, using a toilet, walking barefoot on the carpet, etc... of stuff that THOUSANDS (possibly millions) of people JUST USED RIGHT BEFORE YOU! This is why I am NEVER cheap with the hotels that I choose. I assure that I"m paying them enough to pay their staff to do their jobs right. It's the ONLY safe way to do it!
And here's the old video that I made with some GREAT advice on how to sanitize your hotel room BEFORE using it!
