Went on a cruise in January. 6 days, I got Covid on day 4 and my wife and I were then quarantined in a deck 1 cabin in the forward end of the ship.
Covid for me was just a bad flu. I slept most of the 2 days, but my wife was quarantined with me. She almost went bonkers being stuck in the cabin.
She did come down with it a day after the cruise, much milder than mine. No complications going home as we drove to the port.
At the time we had a 16-day cruise through the Panama Canal scheduled. We cancelled that one. If 2 days in quarantine was rough, imagine 10-12 days. No thanks. FYI, that Panama Canal cruise did end up being written about in news articles because a lot of Covid did occur on it. (Long voyage, older demographic)
Never really knew who I caught it from, but I did have a suspicion of one particular couple we talked to on the ship.
Prior (48 hours) to the cruise we had both tested negative.
