Based on your rate, I would suggest la jolla or  downtown.  Some girls like to go to mission valley or maybe mission bay area, those girls usually charge less.  I don't think those are good choice for your clients.

Well, if somebody considered you an upscale tourist then I guess La Jolla is a good place.  To those of us that live in the area it is a bit of a pain to get to.

I have probably seen a dozen or so ladies that have traveled to our city and those that I saw stayed in hotel circle, downtown or Mission Valley.  These are the places that are most centrally located to the city of SD.  If somebody were from North County than La Jolla would be fine.  The thing about beach communities is that they have limited access and present traffic problems at certain times of the day.  

Like I said, if you plan to be a tourist and fit in some work, then a beach place is fine.  A bit of a compromise for the water and easier access may be some place like Mission Bay.
