Right, Captain Ban was the alternate Captain, my mistake. I believe Claus Andreson was the captain and he moved on to other ships after the incident.
One of several threads from the time:
Captain Ban is still at the helm of Q class ships and no, sales didn't go down on Athem or other ships after that incident (106.4% occupancy in 2016, the year of the incident and 108.4% in 2017). Folks have short memories, despite the media hype.
No, call C&A directly and tell them you sailed on a solo booking -they may tell you their system says otherwise at which point you'll have to take up the issue with your TA.
The policy since early 2020 has been that you no longer get the extra point for solo when you have a booking for two and a no show for the second person. The booking needs to be modified to a solo booking before sailing to get the extra points. Anyone that got the extra points for a now show since then is rare and were just lucky.
You may not have removed her properly to turn the last booking into a solo to get the extra solo points - the booking needs to be converted to a solo when removing the second person. There should be no charges (though RCI may want to reprice at current rates) and yes, the fees should be refunded.
