I have never seen a provider who did not verify me prior to giving me hotel information and then only immediately prior to the appointment.  I have never communicated in writing or verbally regarding compensation.  

IMHO you made the correct decision.  Forget about it and move on.

just as long as they don't give you the room #.

Some girls I know stay at hotels that are next to each other and soon as you get there they say it's the one next door to do a le check on you.

Are you concerned about the fact she was hosting out of a hotel or are you concerned about her not taking the time to verify you ahead of time? Many ladies host out of hotels and I know sometimes we have different ways of verifying clients. For instance, if I meet someone off of a verification site I use, I won't always ask him for a reference because I can easily look up his information.  Just my 2 cents

Over the years I've had many providers give me the hotel name as we were arranging the date. The key, she didn't give you the room number.  

If so, prob you over reacted. However; I personally do not disclose my in call location until screening is done or I've seen the client before, but I am sure there are other well-reviewed providers that feel comfortable giving the name of their hotel and there's nothing wrong with that.
