Have to say I have thought deeply about my personal responsibility and the good for all more than usual now that we are signed up for a cruise. I can only do so much and trust that it will all work out. That seems to help. We did buy travel insurance and check that we have medical coverage overseas to be prepared. We will do what it takes to deal with viruses, the social distance thing, masking in crowds, choosing outdoor activities to try to protect ourselves from getting infected as well as others. You know what we have been doing for the last 2 1/2 years. What more can you do? I think it is likely that most people do their best with their situation and so cannot really judge others. I cannot predict what will happen on our trip, just hope for the best. And hope to have fun, meeting people, making new friends, enjoying the ports and activities. Wishing the same for everyone. Cheers!
