American flight attendant Alia McIntyre uploads tips and tricks about staying in hotel rooms. "I'll never stop doing my regular security routine," she says in one of her more viral videos.
She ends the video by demonstrating a method by which she prevents strangers from entering her room. "It really doesn't matter who you are or what country you're in – you have to have different safety measures when you enter a hotel room," McIntyre says in another video. "This method is 'lifesaving,' if you want to keep your curtains completely closed, use it"
