Lax commuters
I've been based in LAX for 17 years and currently stay at the Hacienda when I have to breakdown and get a room. I don't have to do reserve so I don't usually need a room for more than two nights a month or so. The airline rates start at $55 and tax. They will drop you off or pick you up at Imperial or cargo or whatever. They have a 24 hour shuttle service with a Supermarket across the street.
Howard Johnsons is cheaper but the neighborhood is iffy imo.
