A lot of good points there smiths, thanks.
I have two pre-bookings for next week. For each of those bookings, the girl is well know and well-reviewed.
I politely emailed and then submitted a request for the desired time, date and duration through the AW system.
One girl replied by AW email the same evening, the other the following day. Both sent their phone numbers. I therefore believe that those appointments are confirmed and have always made the assumption that I would call on the day when they are checked in at their apartment/hotel for the address.
I did that this past week with Maggie, with Adele and with Emily.
In other words, I received nothing more from any other girl I have ever met through AW than I received from Cindy.
