I totally forgot about Limo Liner. I'm thinking of taking it this Thursday morning.
My NYC->BOS leg I was in the left aisle (single seat, no neighbors on either side), which was a much much more enjoyable experience than the BOS->NYC leg when I had to sit next to neighbors in the back-right of the bus.
Oh yes, unlike the Chinatown buses, I don't recall the driver talking on a cell phone the entire time.
Just bought my ticket (somehow Amtrak let me cancel my Accela ticket) for Thurs. We'll see how it goes =)
They provided tea, coffee, water, and they provide you with a decent snack; a decent wee sandwich that's much better than you'd get on the train. It's not enough food to substitute for dinner (maybe they'd give you a 2nd sandwich if you ask), but enough to keep you going till dinner.
