Week before Christmas, I was in California. Sacremento's airport is nice. Small and everything's nearby.
My return flight was LAX. The Hertz return section is weird. You pull in and there's really no signage for "RETURN CAR HERE" besides the usual "this is where you go from off the road and don't backup or the tires will be shredded." I ended up parking in a space, noting my own mileage and fuel and walking to the shuttle bus. San Fran's wonderful fully lit garage with people and clear signage is worlds better. They also don't have a highway ring road like most airports. LAX is much like Manchester New Hampshire's. Just z sort of a city street and all in a sudden you're at the airport. I can't give a proper review of the terminals at LAX because a lot of it was under renovation. Signage was clear, no pigeons like Newark, and cleaner than Laguardia. Fuck Laguardia.
I'm quite surprised for as big and busy as LAX is, it's set up externally like a small regional airport and not like a big international hub like O'Hare, Seattle/Tacoma, Atlanta, or Miami.
