Agree. I have occasionally booked on board. Some times worthwhile, others not so much. Tend to wait for late deals now as I am more interested in the cruise price, not the amount of OBC.
Started my cruising with Celebrity in 2011 but switched to other lines after 11 cruises with them. They were just too expensive and not at all solo friendly. Have stuck mainly to P&O since as it suits me better.
Many areas on Aurora were extremely cold during port visits, particularly overnighters. My cabin was cozy but corridor outside was freezing as I was two decks above the gangway opening. But only to be expected when in the Arctic in Winter!
Nothing kills norovirus except strong bleach (for sanitizing surfaces - not recommended for your skin!) Only hand washing (properly) with soap and warm water will remove the virus from your hands. Wish the ships would explain this to pax (although some will not take any notice anyway!) Just best to look after yourself.
