Expanding upon what Jaimito said above, were you ever at that hotel?
If so, you should name it, as it could likely be an insider selling the information and one would not want other FTers exposed to this sort of risk.
In addition, how did this guy pay for the room. If cash, I would be quite suspcious, as rarely is cash used these days.
Further, how did the guy check in without showing some sort of ID?
And, if he used id, and/or paid with a credit card, get the name, etc.
Keep us posted!
