Paris to Normandy trip then 12 day cruise to British ....

I would wait until the last minute that you have to make the decision depending on how much money you stand to lose........I would make every effort to go. It is a wonderful trip. Last April, just weeks before the 75th anniversary of the D-Day landings, we rented a car in Paris and drove to Bayeux for 5 days. We took an extensive tour of the landing beaches, spent a day at Mt. St. Michel, and enjoyed just hanging around the area. It is also a good place to go if you want to avoid crowded places (Normandy, not the cruise ship).
