I have cruised
DCL eight times (twice since reopening) and never gotten sick during a cruise. It can happen, of course, but it can happen anywhere. DCL consistently gets top marks for cleanliness when its ships are inspected by the CDC's Vessel Sanitation Program. Cruise ships are often caricatured as "petri dishes", and some might be, but I would not characterize Disney ships that way. In general I don't think theme parks, preschools or elementary schools are lesser illness vectors than a cruise ship.
That said, I always take a few precautions during any kind of travel, just like as an elementary teacher, I take precautions in my classroom. They are more to prevent colds, strep, flu and noro than Covid, since the former are often spread by touch, unlike Covid. Here's what I do during travel:
- I bring sanitizing wipes with me onto the plane, and into the hotel room and cruise stateroom. I wipe down the common touch points (the armrests, tray and buttons on a flight; the doorknobs, TV remote and light switches in a room, etc.) upon arrival.
- I am scrupulous about washing my hands right before eating. Washing hands in the stateroom before using the elevator (and touching the buttons), for example, isn't enough.
- I bring zinc lozenges with me to use in case I get any inkling of having a cold. I also bring some basic cold medicines in case someone comes down with something, so symptoms can be treated immediately before they start getting nasty.
- I don't choose to wear a mask where it is not required, and during my spring break cruise, it was not required, thank goodness. I don't wear a mask on flights, and have flown several times since reopening without getting sick. That said, I have taught elementary school in person since fall 2020 and still haven't yet gotten Covid that I know of. I have had colds and possibly flu (always caught at work), yet always tested negative for Covid.
I hope you have a great cruise!
