What I would like to see:
Temperature Check prior to boarding and through-out the cruise. (Full body infrared Scanners/Hand Held Device) if there is a problem-one goes for a further screening) Ditto for Airlines and other mass transportation
Daily Temperature check of crew.
Higher criteria for cleaning. (Is there an ultraviolet light/wand that crew could use to make sure surfaces are effectively cleaned?)
Utilization of sanitation wipes. (I know flushing is a problem-aren't there wipes that disintegrate like toilet paper?)
Update/Enhance Medical Facilities and Personnel on ship
Have protocol in place in regard to large illness outbreak on cruise ship and which ports would accept these ill passengers.( No more floundering ghost ships that no country wanted)
Honestly, I can't think of any restaurant on land that I have ever gone to that told me to wash my hands before I entered. Cruise ships personnel have constantly reminded cruisers to wash hands and use the sanitizers.
Since, there has been such negative publicity in regard to cruising:
Invite Youtube 'Influencers' to cruise, especially those with families. Let them highlight cruising.
Forget doctor notes and age discrimination
