Flight
John Wayne Airport (SNA) is located in Costa Mesa, CA. It's in the County of Orange and it's the closest airport to the venue. If you have accommodations in Orange County, this would be the best airport to fly into.
Flight
Los Angeles (LAX) Airport is about a 45 minute drive to Orange County (without traffic... but there's always traffic). With traffic, it can range from one hour to two hours. It would be best to book your flight in the morning, or in the evening (landing after 6:30 pm).
Flight
Long Beach Airport is small, and very accessible. It is closer to Orange County, so the drive is definitely easier to make. Only a few airlines fly into here, so if you aren't picky about your airline preference, you may get lucky with a sweet deal into this airport.
Train
We've taken the Metrolink multiple times, and also the Amtrak. Both the Metrolink and Amtrak travel all throughout Southern California, and many other places. However, taking the Metrolink from Orange County to Los Angeles is around one hour and the Amtrak is 45 minutes. These are both great forms of public transportation to take a trip from OC to LA.
