I'm in a bit of a bind. I will be in SD at the end of this month and staying at the Sheraton Hotel and Marina. I will be with colleagues so cannot do outcall to my room. Is there any incall close by to that area? Any help or advice appreciated. You can also email [email protected]. Thanks.

If by close you mean walking distance, you are out of luck.  The Sheraton is on Harbor Island which is all hotels and restaurants.

If you can grab a cab, lots of ladies down in Mission Valley and the cabfare won't kill you.  Good luck.

Couldn't find Mission Valley on map. Is there an intersection that I can plug into Mapquest. Do providers ever stay on harbor Island? Thanks.

It's an area that stradles Interstate 8 roughly from Interstate 5 to Interstate 15.  Technically, some of the area in that strip may not be considered Mission Valley but it's close enough.
