We walked the Camino from Porto to Santiago in September, then did a Viking river cruise on the Douro (it starts in Lisbon). We enjoyed it alot. However, a couple days before it ended, I got Covid. My husband did too. Viking was very dismissive of it and not caring if we exposed others. They would've been fine with us continuing to eat in the dining room with everyone else (there was one seating). We wanted to be kind citizens and didn't want to give it to anyone else. We asked Viking if we could eat outside; they said no, because then other people would want to also. So, we had them bring our food down to our small stateroom and we ate there. We are planning to go on another Viking river cruise, but next time I will mask whenever on the bus, and possibly while in the dining room except while eating. As much as a drag as it is to wear a mask, I hated getting Covid and having to cancel the last week of our vacation plans.
