My 2 cents (which means nothing!): I tested positive as soon as we got home from our Discovery Alaska cruise. On the plane ride home I suddenly was unable to smell anything, and I knew soomething was wrong. Over the next few days I was very ill, and am still dealing with side effects. My kids were fine, husband felt a bit ill but wasn't positive when we got home. Looking back, I have the terrible feeling that I had COVID for most of the week and just didn't realize it. I was very tired all week, and I blamed it on time zones and just finishing a diffucult school year and finally being able to relax. My husband was also passing a kidney stone for the first few days of our trip, so I was focused on helping him. The only symptom I had was extreme exhaustion on the ship. I didn't get really sick until I got home. I'm sure I passed it on to many without knowing. We wore masks anytime we were around others, and I was super diligent about washing hands and hand sanitizer. You just can't out run it forever. When I was so sick, I said I would never cruise again because I truly felt so bad. But now I feel better, and I'm ready to go again. Both Princess transfers from and to the airport were completely packed, and many were coughing. If you are cruising, there's a chance you'll get Covid. There's also a chance you will have a perfectly wonderful vacation, like my kids did. We saw amazing sights and made memories. I just wish I wouldn't have gotten so sick.
