On the Amtrak website, they list all specials. You may want to consider joining their Amtrak guest rewards program, you get points for travel and shopping through their website (no fees). Eventually you will get free travel or for the auto train you can pay for car and room/seats with points separately. We haven't paid for the autotrain on our last 2 roundtrips (spent $300 to upgrade to a roomette and that was it.) PM me if you want an email link to join or try their site. We love the auto train - hope you enjoy it too.
