Tricky one, and something like this was on Facebook, and the outcome wasn't nice. So a father and his 16 yr old daughter, checked into a hotel, and the receptionist, was suspicious of this.
The receptionist, phoned the police, and they arrive, and the door was open, and the father was arrested, seeming on the grounds of grooming this girl. The father was questioned all night, and his daughter was in tears, and the police wouldn't believe what the father was saying "This is my daughter"
So if your seeing this person, and taking here somewhere for the night, maybe nest to be cautious
