A couple of days ago I decided to make an outcall appointment with  provider who had a few TER reviews. So I checked into hotel and called her. She was available and I gave her the address. She asked me if I was with LE and was satisfied with my firm NO answer. Shortly  she texted me that she is 10 minutes away and I texted back the room number. After 20 minutes of waiting I texted her and she replied that there was police car on the hotel’s parking lot and she is not coming. I looked at the window and yes there was a police SUV slowly moving on the parking lot clearly checking all cars. I realized that I made a mistake by getting into this cheap hotel. First, it is more liked to be patrolled. And second, my new BMW definitely looked foreign on the parking lot. Well, lesson learned.
What do you think in general, what are the chances to be busted during out call

A "few" TER reviews don't cut it for newbies. And by "few" I assume in the single digits?

Cheap hotels will keep many of the best providers away and with good reason. If you are driving a BMW, and a new one to boot, I'd pony up for a nice, upscale hotel or at least a mid-level one.

Outcall or incall, the chances are VERY slim of a bust IF you do your homework. I would contend and most would proly agree that outcall is somewhat less risky than incall but still only marginally so.

See girls with tons of reviews with reviewers who have written many reviews, pm a few of her guys for further protection/info (get VIP here if you don't have it.) and learn to cut down your risk in the future

Assuming that your escort was a real escort, and not some undercover cop, then your chances of being busted in this scenario were exactly 0.000001%.    

Hypothetically, if he sees some woman entering your hotel room, he didn't witness anything illegal, in fact she could just be your wife for all he knows.  For that matter, he doesn't even know for sure that a man is also in the room.  In order to witness anything illegal, the cop would pretty much have to be standing in your room, literally witnessing someone pandering for money in exchange for sex, or some guy offering money for sex.  Then he could bust you.  If he didn't witness these things, you could certainly tell the cop that it happened afterwards, then get busted that way, that is where the 0.000001% chance of being busted comes into the equation.

Most likely, the cop was just driving around the parking lot with an automated license plate reader, scanning license plates looking for stolen cars, etc.  A shitty hotel would certainly be a good place for a cop to do such things.  I sometimes see cops doing the same thing at mall parking lots, walmart parking lots, etc.  

Unrelated minor issue though, if he scanned your license plate there, then there is technically a record that exists in a computer database somewhere that says your car was in that parking lot at that date and time.  That is more of a general privacy issue though.  

and with incall, it's just the reverse.

Yes, do avoid the 1 and 2 star hotels, especially the kind where the room door faces a parking lot.

You'll do much better at a nice urban hotel where there is more anonymity.

I have to agree--stay away from cheap hotels.   Also, NEVER meet the lady in the hotel parking lot and give her money so that she can check in.

When you're PMing her reviewers, what sort of stuff are you asking? Beyond "was she LE", of course.

The problem with reviews is that the girls can see them too so many guys tend not to be as honest, grade with a curve, don't want to hurt the gals feelings, don't want retribution for some of them demand personal info when screening, etc etc etc

So pm is really valuable. You will get a guy admit that maybe the 10 he gave a girl really should have been an 8 for looks. Maybe the 45 mins of heavy DFK was only 10 minutes.  A little more honesty on her weight. Those kind of things.

Many guys also like to ask about personality by pm as that is important to them. Some guys, being new to this or not, what a take charge kinda girl and others want the girl to follow the guys lead.  

And just for the record, I have never asked a guy thru pm if the girl was LE. Just him getting back to me, and hopefully 3 or 4 other dudes, plus her reviews and maybe a guy that I know bc that has seen her is all I need. Sometimes I have relied on one guy if I know him well with no reviews for the girl but that is more "advanced" hobbying, and I would never give that advice to any newbie.

I think the concern is that if there's one cop on the premises that there are more and that she was worried that the guy in the room was "undercover" LE.  Cop in car checks vehicles and people moving about; cops in other rooms waiting to pounce; cop in THE room waiting with handcuffs and Miranda card.  SEEMS VERY UNLIKELY in this situation.

If she was too nervous, it might not have been good anyway.

Now, about the BMW.  I travel through all kinds of neighborhoods and how often to do I see the new BMW in the Mickey D or White Castle parking lot and some young slob with his pants down to his knees steps out.  Drug dealers and other low-lifes who can't even get a credit card (drugs are a cash biz, you know) for an upscale hotel probably park their Beamers at the cheap hotels while they do a deal or shoot up.  I do not think that the LE "Beamer Alert" is about some rich guy choosing the wrong hotel for a date. I think it's about drug busts

but the OP was asking about "his" risk, and his risk in that situation was for all practical purposes zero, unless of course the provider herself was working with LE.
