There is alot more to this story, but I want to be as generous and kind to the provider who will remain nameless.  There was something that caused me to leave the room early, but she was cool about it with the understanding I would come back.  When I came back and knocked no one was there.  I left and came back in 15 minutes and no one was there.  Yes - my phone was in the room still.  I have tried to contact her, but with no luck.  Any ideas?  I'm afraid to ask that question.

That or the bell hop tonight. Slip him a $50. Most know they have a provider working there. Slide him a $50 and get your shit. If you want to be a little quiter about it wait till about 10 in the morning try calling her and when she doesn't answer to phone call or email ask a maid to open the door to your room for you because you forgot your phone.

Email and PM her tonight and then try to text + call again in the morning.  
If that fails then yeah do what YeaThatGuy suggested.  
This is why I always do a  "room check" of sorts before a gentleman leaves my incall.

One swiped my phone charged a few months ago.

I am thinking of just calling the hotel around noon and giving the story that I had helped the occupant of the room with her car and I went with her upstairs to get a number and that's when I left my phone.  It's not like they can prove what we were actually there for.  Is that too outrageous?

A few things I almost forgot my phone in the room too.  Lucky for me, she reminded me to take my phone.  Now, as to what to do, I would continue to call, text or email the girl until I reach her.

I talked with her, but this girl has serious bipolar issues or is an emotional wreck.  A review will come later to warn others.  I just shut the phone down.
