At the risk of sounding like sour grapes (since I'd have liked to have ridden this but could not), I'd hold off a bit longer before pronouncing
it as a "success," Certainly from all accounts the on-board product (despite a few flaws noted in this thread) was a success. It was certainly
a success in the sense that it even happened in the first place, much less twice.
But while as a taxpayer I'm happy enough to help subsidize useful, safe, efficient rail travel to large cities small towns alike, I'm a little less thrilled
about subsidizing excursions like this. So I'd really like to wait to see if this trip "broke even" or not before I call it a success. Yes, I realize there
are intangible benefits to a trip like this, so I'm okay with perhaps a slight operating loss...but I really don't want to find out later that the $89 tickets
only covered roughly 50% of the cost (for example).
And yes, I also realize that many folks who rode this also took Amtrak as a positioning trip to/from Philadelphia. I'm happy to factor that into the
"success" of this trip, too. Bottom line is, make a case for doing this again beyond simply "the people on board had a nice time."
