For 6 months last year I was consulting in Los Angeles with Echo Networks. I decided that the only way to go was to take Amtrak. Last week I was in LA for the day on business and decided to use my pathetic camera phone to snap these pics shown above of my trip.
Anyone who goes between SD and LA should consider the following:
Train between San Diego and Los Angeles.
From here you can either rent a car from Budget, or take the Red Line subway to the 7th street exit, and walk over to the Standard Hotel. They can arrange to have a rental car available for you in the morning.
It really is the only way to travel. A couple of hints, reserve the cheapest car at Budget. They are set up for excursion travel and many times I get a Town Car or a convertible Mustang for the price of a Hyundai. The other hint is that all the rooms at the Standard are great. I stayed last week for $99 and was instantly upgraded to a medium room. I love this hotel. The rooftop bar is a must see and it is almost always 'going off'.
