This, so much this. I live in Nor Cal but grew up in So Cal. I have made that drive at least 100 times over the years, and it is a long boring drive. Getting on a plane is fine, but when you take the drive time to the airport, arriving ahead of time, getting off the plane, the total time is probably close to 3 hours even though the flight is only an hour or so. So while I prefer to fly down there if I can, it is a huge pain in the ass if the whole family goes (7 of us total), and expensive as shit.
If this is really a viable, relatively cheap alternative, I would be all over it. My mom would love it because she could come and see the kids every weekend if she wanted.
