Thank you, of course I read this thread before posting here. It does not answer my questions though!

"Whom shall I contact to reserve a LH-FC-paid room at the Kempinski? Kempinski or Sen-Hotline? Which Kempinski are they referring to? Gravenbruch or Königstein? How can I arrange for a pick up with the arrival service?"

I t would be of help to learn the exact procedure and even more important, which Kempinski hotel is involved.

Before I posted the question here, I searched this forum thourougly but could not find details, neither at lufthansa.
