We have just returned from the Paris to Normandy trip on the MS Bizet with the post trip option to Brittany. It was a good trip despite the fact that the temperatures were in the 50s and it rained almost every day. We dressed in layers, carried our umbrellas, and needed our hats and gloves at Normandy.
I want to comment on the optional excursions for this trip. We didn't do the Louvre or Versailles as we had visited those places on a previous trip. If you haven't been there, they are quite impressive!
The trip to the Abbey at St. Wandrille was disappointing. The buildings are old, older, and oldest but you cannot go inside to see where the monks work, eat, or live. The tour was led by a monk who spoke in French and the Program Director translated. This is a working monastery so the modern gift shop sells some of the products they make. I would skip it.
The Cliffs of Etretat and Fecamp option is another one that I would skip. The cliffs are wonderful white, chalky cliffs overlooking a pebble beach. There's a scene that you see on all the post cards. If it's a beautiful sunny day you can walk the beach or sit on the "boardwalk" and watch the waves and the people. When it's cold, raw, and drizzly, it's not such a good trip. At Fecamp you learn about Benedctine. However, this never was an abbey or a religious building. It's a monument built by a very wealthy man. It is interesting to see but.... Skip it.
The Bayeaux Tapestry is a must see. This is actually a very long piece of embroidered cloth that tells the story of 1066 and the battles and William the Conquerer, etc. It's amazing that it still exists. You are given an audio device that explains each panel of the "tapestry." There is a pause button so you can study the panels as you walk by. This was our favorite optional tour of the trip. It's definitely worth the long bus ride to get there!! Don't miss it.
Dinan, a medieval city, is the optional tour on the post trip extension. It's an interesting city with half-timbered houses. However, St. Malo has very similar buildings and unless you have a real fondness for this kind of architecture, I would use the afternoon for browsing in St. Malo or, if sunny, for relaxing on the deck of the ship.
Honfleur is a great city for walking around and exploring. Use a free afternoon to "get lost" there. The same goes for St. Malo.
There is a lovely neighborhood restaurant around the corner from the hotel at St. Malo. It is called La Hoguette. They speak some English and even have a menu with some English. Their specialties are "moules frites" - mussels and fries - and pizza. We ate there two nights and tried both. You can't go wrong with either choice.
If you have specific questions I'll try to answer.
Mont St. Michel is amazing! Yes, there are hundreds of steps but they are scattered. Everyone is our group was able to go through the whole area. And, remember, lots of those steps are coming back down!
