We have a NCL cruise booked for 12/21 and a X booked for 2/22. If the cruise lines don’t require proof of vaccines we’ll cancel. Why would we go through the past year of Covid protocols to get wrapped up in a Covid outbreak on a ship thousands of miles from home? We’ll be vaccinated and protected but if any of the anti-vaccer’s on board test positive the vacation everyone has been planning and looking forward to for the past year will be over. Then you can look forward to a quarantine, early disembarkation, looking for hotels, flights etc. Not to mention the financial loss.
