My wife and I have tried out the AutoTrain sleepers and found them not worth the extra bucks. We thought we found an answer: buy an extra coach seat so that we could at least try and stretch out over the two seats and their leg rests. It now appears that Amtrak won't allow the purchase of a second seat. My question is: how would Amtrak do if I bought a seat for me and a accompanying companion while my wife did the same. I seriously doubt that anyone would seek to buy a coach seat and a car reservation 2 hours before departure. So, when I check in (2 hours before departure) and the adjoining seat that I paid for is empty (because of a no-show companion), what will Amtrak do? Refund the cost of my companion's seat OR allow me to keep it since I paid for it already? Wouldn't Amtrak want to keep the cost of the seat as opposed to allowing the train to leave the station with an empty seat and no revenue for it? What do you Autotrain riders think?
