I never let anyone come directly to my room the first time I see them until after I have confirmed they are indeed the person in the photo. I'm very straight forward when I book them and say I will meet them in the lobby or coffee shop/bar and if they are the same person in the ad great, we will go right up to my room, if they are not, they will be asked to leave. I always do it where there is someone around so they will not be tempted to throw a punch or something. YOU have to control the situation, don't let them bully you.
