This will be a Viking River Portugal Duro River cruise with a pre extension in Madrid Spain
Debbie and I have always wanted to do the Duro River cruise. Now that the COVID restrictions have eased we have booked it. Dealing with Viking has been uneven. Viking does it all in house from flights to hotels to tours. All you do is show up after paying. And you pay way in advance but you are treated very well. The web pages are well organized but sometimes out of date so it behooves (what a word!) you to check back frequently and recheck their links to other countries entry requirements. Sometimes things change and they do not update as quickly as they should.
