Started Wed June 13 in Lisboa. Met at airport and transferred and given handout for restaurants etc around hotel. Site representative and most folks start the next day.
We visited the zoo on Thurs. Briefing was Thurs night. Fri was city tour in am and on own in PM (too few picked extra cost optional). Sat was on own or optional extra cost guided tour.
Sun transforms to visit with stop at Coimbra Univ. Then finally on ship at Cais Gai.
Trip ok. Problem for me is other than visits to Port vineyards and hearing about port wine, there didn't seem much of interest on the Douro. Maybe that is why the start in Lisboa and day trip to Salamanca. And after getting to Salamanca we were mostly by ourselves.
Memorable events were the visit to the Archeolgical site at Coa (NOT for folks with mobility issues), going through the Carrapatelo dam (2nd upriver from Porto) the deepest in Europe and "Mr Bean" at the dinner at the Enoteca da Avessada.
The most memorable was an accident. The ship was docked at Cais Gai the evening of June 23 before Sai Joao day. Great fire work display at midnight right in front of us from boats in midriver and the bridge.
Unlike others I really like the diff Portuguese food. And one could always ask for e.g. the striploin steak and fries etc from the alt menu.
Only oddity was the flushing mechanism. Room attendant Rosa was excellent.
