Food not that great. Too much riding buses to excursions. COVID spread on ship probably due to overcrowding on bus to sites. Crew very nice. I would not recommend this Douro cruise. Excursions not that interesting. Archeological museum tour, there was no museum, only viewed rocks with scratches. 7 km dusty, pothole filled ride to site on overcrowded Toyota SUV. This was after a one hour ride to board the Toyota SUV to the site. Pre cruise literature did not advise that it was a two hour bus ride to Salamanca.
Bus ride from Porto to Lisbon indicated stop in Coimbra for lunch. Tour stoped instead at Obidos, small uninteresting town. No explanation ever given for the change.
Several passengers that tested negative on embarkation tested positive a week later. Restaurant probably source of contamination.
