Have you ever been on vacation or a business trip and have stayed in a Hotel/Motel? What crazy types of people have you run across?

Every person has a distinct personality, and this is very much the truth when it comes to people on vacation who are staying at a Hotel/Motel.

Some people are quiet, and keep to themselves, some have kids, or animals. Then there are people that I call the "crazies". These are people who are simply annoying and you just wonder why you decided to stay at this particular place, or made you wish you hadn't at all. Have you ever experienced this? What types of people in Hotels/Motels do you find most annoying?
