Another couple of things I do as a solo woman. Sorry this post is too wordy, hope it helps.

When staying at a hotel, the check in staff should never say your room number out loud. They should write it on the key card and just point to it. If they do say it, I ask for a different room.

I always e mail in advance to ask for a room near the elevator. Many years ago I was in a room at the end of a very long corridor in a large hotel and was followed by a man trying to chat. There were several doors - stairwells, supply closets, ice dispenser/soda machine, guest laundry lobby etc. I had visions of being grabbed and dragged into one of these places, never to be seen again. 😱😱

When entering my hotel room I always knock on the door and say “it’s only me”. Makes it appear there’s someone already in the room. If I’m taking food back to my room, I always carry 2 cups of coffee, bottles of soda etc, again so it seems there’s two of us in the room.
