I have nothing to add to the musical discussion, but I travel Amtrak a couple times a year from DC to NY, and have never paid more than $175 round trip, even at Christmas.
Thanks again... and oh, are you lucky, being so close to Mexico. I'm on the East Coast.
Yes, it's only a two hour flight to Mexico City, whereas it's over three hours to New York.
Flight time's one thing; cost is the other. (I bet that's true for you as well.) it's funny how Amtrak and the airlines seem to jack up prices in an arbitrary way. When I lived in D.C., a round-trip train ticket to NYC cost several hundred dollars. Now I live up in PA< and a round-trip ticket to NYC costs less than 100.00 bucks. (Though I'd have to change in Philly to get the Metroliner or Acela.)
Basically, Amtrak ticket costs are far higher if you're *only* traveling on the NE corridor lines. Book a ticket from a bit further west, and it's so much cheaper, even though you're actually on a NE corridor train. Go figure!
