She is highly rated and all positive reviews. I get a text at 1015 asking if we can do tomorrow? Come on...that's lame. I guess thats the difference between 400 an hour ladies and 700.  

When I got home afterward, I was bummed and pissed.  And had an e-mail from an ATF disappointed I wouldn't be in Vegas that week-end.  A complete 180...90 minutes later...flight, hotel, and rental car reservations made. Great week-end followed!

I think it does. Providers charging 700+ per hour will not treat a client this way. I also believe they wouldn't be scheduling back to back clients.

A 600/H lady who canceled AFTER the start time of the appointment.

How would she respond if you cancelled 15 minutes before the appointment? I hope she'd be cool with it

With price point which is my only point here. It's crappy either way.  

No provider is worth $700, only if you are into S&M and She have to do all the work, maybe, but $400 to $500 is the fair rate and you can find the best for this price. IMHO
