I just need some tips as to what part of the city to stay in. SOmeplace safe, but close to the sights.
What sights? L.A. is a huge area, incomprehensibly large compared to most cities. There is basically a continuous urban zone from south Malibu to Camp Pendleton, all of which is considered "L.A." to some extent. (The Orange County residents will dispute this, but for metro areas, it's generally true).

What did you plan on seeing in LA, I might be able to give you some ideas where to stay.

OH!! Just remembered. If you are in the San Diego/LA area May 6th or 7th, Celtic Woman is touring here.
