Don't switch! $1000 is A LOT of money. We typically use SNA but flew in and out of LAX for the first time a few weeks ago and it was fine. I was quite worried considering all the "avoid LAX" sentiment on the board, but we booked it because it was cheaper and from a better departure airport for us. After using LAX, I really don't understand all the complaints. Other than the distance to DLR (which was a bummer, but we knew that going in), it was fine! Security was quick, airport was clean and easy to navigate, etc. We rented a car so can't speak to using the Resort Express, but made it in and out of the airport with 2 kids, 2 carseats, a stroller, and luggage with no issues.
