I just finished my weekend in Vegas a learned a few lessons the hard way I thought I'd share. First, if any of the well reviewed ladies strike your fancy then book them as a first choice. ALWAYS have a plan B or C appt as backup because they aren't dependable as a whole.
I had a whole list of ladies I wanted to see (austin, gia, ashley, etc.) b ut I couldn't get them to return calls despite several messages and carrying my cell phone around. I did book Austin once for the next day, but she no showed.
I ended up calling an agency.Thought I'd just see what was available and if something looked good, negotiate as best I could. They ALL say a thousand at first. Yeah right. Don't apy anyhting up front. Dress in a towel or underwear or expose or lay with yourself so they are comfortable you're not a cop. Have airline tickets etc out in plain view. Make sure you have condoms, lube etc out in view also. Now she's pretty certain you're not LE, you need to be as comfortable with her. Tell her before you discuss finances she must lift her top to flash a tit. An undercover cop won't do this. A ripoff chick may not do it, but a motivated provider will. It also gives you an idea of what her body is like without the clothes.
Once you're comfortable with her. Start talking specifics. Be VERY specific. They'll tell you "everyhting" is include and then say that meant you get to come with a handjob or bj or other BS. Tell them you want to DATY or do doggie or whatever. Tell her she must stay the hour or until you come and they'll be more into giving you a better session.
Once you call an agency they'll send girls all night. Stay cool, beat off if you have to, but hold out till you get what you want. Hope this helps.
