Now that Acela is no longer rotating the movable seats, each (business) car has half the seats facing one way, half facing the other way (with respect to the moveable seats). The previous guidelines about good window seats are no longer completely accurate. I meant to do an "analysis" on my last Acela trip of the seats with good window views, but forgot to do it! Sorry about that. Maybe you can do that analysis and share your observations on this forum...
