Interestingly, SW (or any other airline, actually) out of Orange County CA is wayyyy more expensive than LAX. I looked at every single carrier out of OC for the dates we'll be there Jan 30-Feb7, and each one would have been over 1000 roundtrip for 2. We ended up on a flight out of LAX on Southwest for 107 apiece, and returning on Delta for 202 apiece (SW was 333 apiece for a flight that left around 5pm - we are now leaving at 730pmish I think, so more time in the parks). Not bad at all! Unfortunately it is out of LAX though, so a longer drive home for us..
