Another option for the family wanting to visit their acquaintance in New Mexico . . . Fly direct into San Diego (via Hawaii) on Hawaiian Airlines. Rent car for however many days, see the zoo, wildlife park, Scripps Aquarium, Coronado Bridge, seals at La Jolla etc. Drive up to LA. Fly to New Mexico. Rent another car to visit the acquaintance and see the sights. Return home via LAX.  Any clued-up travel agent should be able to put this together.

I was surprised that you didn't advise the use of Greyhound.  Our use of Greyhound has usually been in Canada rather than the USA, Vancouver to and from Whistler and Vancouver to and from Quesnel but we have travelled from Seattle to Vancouver. The buses are comfortable and quite cheap.

My mum uses an app called Calm to fall asleep. It features a 24-minute story narrated by Stephen Fry called Blue Gold and she's never heard the end of it.

Instead of listening to a "boring" app to fall asleep, I recommend you listen to your favourite podcast for the second time. You can drift off without worrying about missing anything.
