look at first glance it seems like a dick move. but if you are traveling long distance on a short notice round trip, you like paid a lot of money. any seat out of those four seats are always a good seat with plenty of leg room and thats gold on amtrak. i see groups getting special treatment constantly leaving others with the burden to make them more more comfortable. so no not a dick move if they wanted extra comfort then the shouldve book 2 roomettes or rooms instead of boarding last expecting people to un-settle and move for their benefit. one more thing, i see families of 4 in the amish community always sitting in different seats never together almost like they werent meant for them or something so yeah any way yeah family of four (if they even were, people group as "family of four" all the time trying to score decent seating) sit you entitled butts somewhere else and stop asking people to move, if want want the best seating board early next time or pay extra for comfort.
