And that's the primary objective. To make the RT auto transport fee as competitive as possible with the RT Fuel tank cost. I'm surprised it has not exceeded that, given the cost of fuel rising these days.
It's good that you could book a ticket. Normally, to get the reservations you want, and the accommodations you want (rooms, etc.), you really need to book well in advance (6 mos), especially if you're travelling during "snowbird" season. Snowbirds are the AutoTrain's #1 constituency. The #2 constituency are families visiting "The Rodent."
