Just got back from an attempted first appointment and I'm wondering what went wrong. Would love your input - maybe I'm just nuts.

Picked a provider that had strong reviews, on P411, and everything looked good. Messaged on Saturday and she quickly responded. We set something up for Monday at 2pm.  

Sunday afternoon - confirmed and said she would send me directions late that evening.
Monday 11am - sent hotel information, but noted the hotel is having trouble getting a room ready for check-in. I responded back with ok.
1pm - texted that they won't be ready before 3pm. I replied back that I had a hard stop at a certain time and asked for updates.
2pm - no response, I texted back that i needed a bit of lead time to get to the hotel.
3pm - no response - I texted and emailed just to make sure i wasn't missing anything.  
3:15pm - texted that if I didn't hear back, I would leave (I was around the corner, waiting at a coffee shop). No response, so I left.

Did I scare her off? What did I do wrong?

I have found that many hotels are clamping down on the 3 PM check-in time, even if they have a room ready.

 
If you are a member of their frequent guess program, they'll cut you some slack.   This happened to me a few months ago at a motel.  My date and I had to cool our heels elsewhere until 3, even though the hotel was no where near full.

But the lack of contact? I didn't think I was being out of line or annoying...

business hotels, are full on a Sunday so getting an early check-in on a Monday should not be a problem.

Might not have been the hotel's fault at all.  
I think you handled it well.  Coffee shop is where I wait after locating  the call point.  

Do I submit a review or something in P411?

That is to say, she had another guy stringing her along offering more money than you, and you were her back up.

 
It sucks, but it happens.   Same happens to gals from guys playing two hands at once.

You got fucked over instead of getting fucked..join the fucking club..

Hookers flake out all of the time.  It won't be the last time if you stay in this game long enough.  Just had one flake out on me today.  Best thing to do is not take it personal and move on.  Not sure if you have access to reviews at all aka VIP, but if you do the best thing you can do is read and do your homework on ladies that you plan on seeing.  

I've had 2 NCNS's before too. One girl emailed me the next day claiming that she dropped her phone in the toilet or something. Might be true, might not be, but I doubt her only way of e-mailing clients is through the use of a phone.

Another girl just went AWOL on me, which is weird because she's still getting reviews weeks after the fact. She's a well reviewed girl too, so I don't even know what happened there.

Maybe you really wanted to bang her for one reason or another but I'm sure there's a similar girl on the market for a similar price. Don't beat yourself over a no-show, ultimately it's a transaction, not a romantic encounter with a potential love interest, so just treat it as such and find another girl. And don't bother trying to set up another date with her either, if she no-showed once, then she might do it again, and I consider that type of behavior both disrespectful and unprofessional. A provider who's cancelling a date should at least give a courtesy text, but if she can't even be bothered to do that much than she's not worth your time or money.  

Omg sweety I am so sorry  
I am 7 to 8 months in  
I know that men have it very hard so I actually in my own way become a pushover when it comes to rates and things no more though but I could understand the hurt I have been rob's I've been shorted of money numerous things have happened to me on both sides there's no excuses I wanna give you a big huge hug great now I am sorry so air hugs I'm dealing with the situation right now aside from this website and the other one that was mention there is an other site that I'm not a while to mention the begins with an E that supposed to be really good because just needs to be more websites again sweetie you did nothing wrong and it just gives good girls like me and other good girls band names and it makes it harder for us and I can understand why some dates come off harsh when they don't mean to I totally understand I am so sorry I just feel so terrible

As someone who has been active for a short while, my suggestion is not to take it seriously. The first one or two NCNS do feel very weird. However, after that and with some experience, you'll learn to live with it and it won't bother you anymore.

 
What I did was after a few okays, I got verified at a few agencies and now have them as a backup not only for NCNS but also for last minute cancellations.  

 
In the past couple of months, had a NCNS as well as a last minute cancellation from well reviewed providers and that didn't bother a bit. Called agency and I was taken care of both times. I do feel a bit weird about outing them out, did that with the first one since I'd freaked out, but don't do that anymore since it is very difficult to find out if one is telling the truth (though sometimes the excuses are just so obvious    .  

 
Like someone else mentioned, not the first time this has happened and certainly is not the last time this will happen. Good luck and enjoy!!!!
