my policy of NOT going to hotel incalls in place.  I only go to residential incalls.  My only hotel sex is outcall where she comes to me.  The room's in my name, so no reason for anyone to suspect I'm a customer.  Its better if they just think I'm an older guy who is good a picking up 25yo girls who just happen to be horny.  You can laugh, but no one has asked me yet if my young date is a hooker.  

From time to time I've heard of hotel employees setting up cameras in rooms to record the patrons' sexual escapades.  
Often these are the one star placed that have rooms that open to the parking lot and have a mirror on the back wall. Behind that mirror is a service chase where a camera can be set up, and a section of one-way mirror installed.  
If you find yourself unlucky enough to be ensconced in such a dump, at least toss a towel over that mirror or you could become the next internet sensation.
