Thank you for sharing. Sorry (but unsurprised) to hear that you were not a fan of the Cardinal's diner-lite. It will be interesting to see how it compares to the contemporary and fresh meal selection on the Capitol.
And they actually did previously run Ocean View seasonally on the Cardinal for a couple years (last time was I think 2012), but for some reason they stopped. As to Superliners, there really aren't (m)any to spare, so I just don't think they would have enough to equip the two Cardinal consists needed, even putting aside the fact that it couldn't run north of D.C.
