I've never made an appointment before my trips, but I have setup appointments while visiting a brothel and talking directly with the lady or ladies for a party to happen later on that day or over the next few days.
Sexy Lexy, Chloe Daniels, Jordan Soprano and Kristen are some that I have scheduled in the past and they all were waiting for me when I arrived. I will say that Chloe went out of her way last summer for me, so that I could have another party with her during my time in Nevada during LPIN Gathering-13, as she was on a multi day outdate at the time.
I don't think I would make a far in advance appointment, or base a trip on one, based on the experience of Geo and others.
Perhaps the thing to do is to politely note online that a scheduled party did not take place, and give the ladies name and reason. I know there are legitimate reasons for not being able to make a party happen as scheduled. If a lady does cancel we need to hear about it and the reason for the cancellation. With more ladies attempting to work from advance appointments it may be time to include that info in reports and a client will need to decide whether to include listing the ladies name or info.
A lady that does cancel should offer to make it up to you somehow, such as offering more time or a discount when rescheduling, assuming that is something you would want to do. If she becomes a repeat offender than we need to keep that in mind if we are scheduling a party in advance. Adding that info online might help others decide if they want to schedule in advance with her.
Shit happens.... it just sucks when it does. But if the same lady develops a reputation for doing this sort of thing over and over, guys need to know about the possibility of such.
Take care,
