I am in Wisconsin for business staying at a Doubletree hotel (stayed here many itme before). Last night someone tried to break into my room. First, he tried to break the lock on the door. Then, he bangged on the door. When I asked who is it, he mumbled some gibberish. I tired to look through the peep hole and he blocked it with his finger. So, I didnt open the door. He stayed at the door for a few minutes and then left. Tried again couple of hours later.

I am think he specifically targeted me since he could have tried any other room and the fact that he tried my room twice, but not sure why.

What should I do if it happens again?
