Safe?

Friends, I am a 61 year-old lady. I’m going to Las Vegas for three days in December. My friend may not be able to go with me. Is it safe for me to fly in, take an Uber, check in at Red Rock Hotel and Casino and stay there by myself for three nights? I know any place can be unsafe but what do you think my chances of something bad happening to me, are? I worry about getting off the elevator alone or the adjoining door that’s usually in the hotel room.
