My wife and I are signed up for the Scenic "Delightful Duoro Cruise" leaving from Porto, Portugal on July 11, 2022. We have not received any final documents from Scenic. When we go on their Booking portal we get a message that our trip is being finalized and the portal is not accessible. When we call Scenic we get a recording saying that one of their travel assistants will be with us shortly. Have waited up to an hour with no one picking up. This is our first trip on Scenic. Is this usual???
