I live near Costa Mesa, It is only a 45 minute drive on the 405 south from LAX. However, the caveat as always with SoCal driving is the day of the week and time of day that you will travel. The time estimate of 45 minutes grows depending on the above. If one were to fly into LAX wednesday eveining prior to the conference, the drive should not be very bad.
Good Luck

i am only worried in the short term. once there is a problem, the solution usually presents itself.
