Recommendations for a visiting Newb?

Hi!

I've never used an escort service before, but I'll be visiting Las Vegas this next week and, well, what happens in Vegas... you know.

Anyway, I'm driving down from Salt Lake City and I'll be staying with my brother, so I'm looking for someone who might have a nice Incall location.    As far as my personal tastes go, I like thin, smart "hot librarian" types.   I'm also looking for someone who might understand the nervousness I expect I'll have as a total newbie.

So any recommendations?
