Switch over to "Satellite" view and go to maximum magnification. You will see a large area of "white sand" abit off to the right. That is the South Lake Beach Club(2 Blue Lake--for some reason this address isn't locatable directly via online maps). The nearby elliptical parking lot is where you can park your car.
You can search 1 southwind, irvine, ca in Yahoo! Maps and then get personalized directions to get to the venue.
