was the double-decker more comfy?
we've done amtrak one way and then megabus on the way back. that way you still get the cool train ride and don't risk two mega-delays.
actually, i don't know. i've only ridden the double decker. i do know i was mildly cramped, with winter clothing (and oh yeah, the heat was out on the bus and it was 8 °F), and being 5'9", 160 lbs. other than that, the seats were soft. Chicago-StL is just too long for a bus for me, though.
i also did amtrak one way, and megabus home (from chicago). i really enjoyed walking around the train, and sitting in the cafe car reading, drinking a sam adams, busting stifled farts alone. meanwhile, back on megabus...
