I need to go out and visit with a customer. I will be spending all day the 20th with the customer at various locations and my plane leaves about 8 am on the 21st.

I arrive LAX at 11:05 am on the 19th and then I will go to my hotel in Santa Ana.

What can I expect traffic wise, and what is there to do in Santa Ana?

I will have a rental car but I have no idea what I should go do.

I really don't care for any bar hopping type of thing but I like to eat and people watch. How far from the beach will I be?
