You will like it! You should do it at least once. Get a roomette, then you get all kinds of privileges such as getting your bags checked for you. This will happen in the big Chicago Amtrack hub when you get there.
Also, with a roomette ticket, you get to hang out in the nice Amtrack lounge there in the Chicago hub, free snacks and cold drinks.
You’ll have newspapers and free coffee every morning. Remember to pack slippers. Also take your own booze if you drink and a flashlight.
the trains west of the Mississippi are better than the east. Western trains are newer and have double deckers with the great viewing car, but not in the east because of the old tunnels.
I think you’ll enjoy it. Anyway, try it at least once.
You do realize that we the taxpayer pay for Amtrack...
