There were some pre-cruise information and package glitches but we were picked up at the airport no problem and the hotel in Lyon was great. The cruise went as planned but several excursions were cancelled or adjusted due to COVID. They did a great job substituting other destinations. Also some evening entertainers cancelled due to traffic problems or COVID. But these were not important to us.
They did not test people for COVID before letting us on the ship. Some people volunteered to be tested because they had symptoms and were positive. They had to stay in their cabins. The ship did not enforce masking. Many people ignored the policy and did not mask. The same with sanitizing, e.g. for the buffet. We were very careful with masking and still caught COVID. Luckily I only tested positive after I got home.
Having said all this, we love river cruising with Scenic and have two more trips booked for 2023!
