Paris is always a great destination. Just walking around the city is a great pleasure. Lunch in a little brasserie near Notre Dame added to that pleasure. And, a visit to Notre Dame is good anytime - a place of peace.
We had never been to see Monet's gardens. This was a reason for the trip. The gardens more than lived up to expectations even though we were too early for the lilies to be in bloom. Our guide was wonderful, very knowledgeable. We took lots of photos, and had to buy a guide to the gardens to figure out all the variety of flowers. (The gift shop was an excellent shopping stop.)
Omaha Beach and the American cemetery were very moving places. Rouen and the smaller towns along the way were most pleasant. And then, there was the simple pleasure of cruising on the Seine River.
As always on Viking, the food was excellent, the service friendly and unparalleled, and the cabins most comfortable at the end of a hard day of tourism. We always like that we unpack once and the hotel goes with us on the journey.
