We did AT on 2007 with 3 little kids and hated it. Had a family bedroom on lower level and it was the front of the car where it attached to next car and was so loud and bumpy. And I was crammed on a top bunk that was tiny.
But we just did it last weekend, again. We live in FL and have all our family in MD and have been driving back and forth a lot...elderly parents with health issues plus holidays and weddings and all that stuff. On our way home to FL after this past Xmas we got detoured off 95 in SC due to massive back up. In the back woods there we were hit hard by a big pickup and it totaled our vehicle. We were stranded as there are no Ubers and enterprises were 25 miles away (one each direction). Rental car was not available until the next day. We had to ride in tow to a McDonald's and hire a taxi at $120 to take us 25 miles to hotel by
enterprise. Took hours in the unseasonably chilly weather too. Plus our car was packed to the gills with our stuff and the windows and all were busted out. All our stuff sat overnight in busted up car.
So no more driving for a while, if ever again. We had booked a flight to come up for a wedding but have some other things to do and needed our car (to bring back some stuff). So auto train it was.
We did a bedroom and booked the week before and lucked into the best location on the train (5241 L). We were top floor in the car next to the lounge car. Nice space for the 2 of us. We could share the bottom bed. We could easily walk to lounge car to sit. Was a way better experience than 2007. And when getting off we had our car pretty fast, like 25 mins after detraining. However it was about 1k in cost. Pretty crazy and not something we can do super often.
We booked for way home too. But had to get roomette because a bedroom was 1500 and roomette was 950. No way am I spending 1500. Now this time we noticed bottom room next to the family bedroom on our car. And might be right next to engine with horn going all night, which I could hear from our last spot (4th car from engine). So I did a chat online and asked if they could find an upstairs roomette. Still not sure how close to engine we will be. They said they can mix the cars up all different ways each trip. It's 5346 (7).
Also we didn't know that they do 3 dinner settings and you pick when you arrive to check in. So the 5pm was gone at 2pm when we arrived. We got 7pm. That was fine. But FYI for any readers here who are new to AT. We had a long car line to get in. Took almost half an hour. We spoke to a lady who arrived early and had to sit as the train was an hour late and they didn't start check ins at 12:30. Hence the back up. So we plan to arrive early next time, drop car and then maybe uber out to lunch somewhere. Heard there are a lot of places near the Lorton station. FYI, sanford station has a food truck. Lorton does not.
