I emailed a PR contract at Cunard and asked about a possible visit for our group when she was in Greenock. I said I could even restrict it to Cunard world club members if they wished - i.e. their customers - but unfortunately it's a no go. No reason given, just no.
I had also thought about doing something in the Greenock cruise terminal, however space is very restricted there so that's not looking possible either.
So as it stands, there's nothing planned.
If anyone wants to arrange a meet up through this forum during one of her port calls please feel free though!
