Louisville (I live in KY) has always been a bit of a dicey proposition, in my opinion.  The Ville is heavy with lots of "sensual rubdown" types who are strictly upsell, and, in all honesty, a ripoff.

Now, throw a once-a-year event like the Derby into the mix, and the place starts crawling with wannabe providers looking to fleece tourists for the weekend (a la Super Bowl wknd). My advice would be to research this board VERY carefully and select only a well-reviewed provider with long-time Louisville reviews.

That being said, there ARE quality providers in the Ville, who seem to specialize in that "not quite Northern, not quite Southern" thing that I happen to find incredibly sexy. Just steer clear of unreviewed "visitors" and you should be fine.
