This sounds like a great event.  I notice you are forbidding the taking of pictures in the event, which I understand, but some attendees may want photos with their favorite performers.  You might think about renting a photo booth so performers could take photos with their fans, without risking anyone being included that didn't want to be.

Are non-porn stars in attendance so it would be like a general meet and greet with TER  providers ?

 I do not see realistically non-porn star TER providers paying $300 to attend. At least the majority. I want to attend but would want many providers there !

My two cents ... it looks like 10 ladies from your agency will be coming.  Of those 10, there are only about 2 that I would be very interested in meeting.  Usually the draw of a m&g is the opportunity to quickly meet dozens of ladies (often 40+).  And often the attendance of screened ladies is free.  The price point isn't unreasonable for gents.  Unless there are more Tyrst ladies (or ladies in generally) this event probably isn't going to encourage many gents outside of LV to attend unlike many other m&g events.  Also, most m&g events do not require prepayment or linking payment to personal information.  Bottom line is that you are competing with other events such as the AVN or Exxotica that allow gents to meet more ladies at a lower price point.

The money for the guys is not that high. I just want to make sure the ladies are not having to pay that. My fear is that would keep them away. I want to plan this as one of my major Halloween M&G affairs. its a big deal to me socially !
