Simba's Mom--
If you can fly into Orange County (John Wayne Airport, airport code SNA for Santa Ana), it is your best bet. It's much closer than LAX and less hectic. I would especially try to avoid LAX during heightened security alerts. Supershuttle costs $11.25 each way from Orange County, and is easy to catch. You can get a reservation online, but you don't usually need one arriving except during busy periods. You do need a reservation returning from the hotel to the airport, but you can call that in from your hotel. A cab costs around $36 each way. (Neither figure includes tips). I Just got back, arriving at the beginning of the holiday rush and returning the 23rd. We had 4 stops on Supershuttle coming (we were stop 3), but it was still quick. Returning we ended up splitting a cab with another couple because we decided to go to the airport earilier than the time of our Supershuttle reservation due to the heightened security alert.
Have a great trip
