Tell whomever you want to chat with when you will be there ahead of time.   I have never used it.  I don't know how many people use it for pre-date chat, so you might have more success using an instant message system, like Yahoo, if you want to chat.  Don't know for sure, just guessing.  Most providers do not take the time to chat with potential clients before scheduling dates with them, as time is money.  If you are very low volume, you might have the time, many do not, or consider it a waste of time.
