I agree with everyone. I was going to say to take a book or a paper, but it's already been suggested. I have done that occasionally in my working years when I had to go out of town for some reason. I will also, like Patze, go to a movie alone if my hubby is away and my daughter doesn't want to come. I would also go on a BUSY trail, nothing backwoods, but that's only being smart.
One of the things I was told is to ask for a room close to the lobby if possible. They will know what you mean, being a female traveling alone. It's comforting to know that the employees are within distance of you calling out for help. Lucy
