The prices may vary. It depends on when you book your ticket and whether you are going to ride couch or in a sleeping car. You can go on the auto train website and you will see the different options and what they cost at the time when you want to travel.
We paid exactly $1835.00 for a roundtrip ticket for 5 adults (which worked out to be $367 per person) but the further out you book your trip will cause it to be less expensive. So that price to vary depending how early or late you purchase your ticket.
