We will be spending a week in Paris, (actually, in the suburb of Vincennes), and my father, (his first trip to Europe, let alone Paris), has told me his dream is to visit a few of the DDay beaches, and of course, the American Cemetery. In reading through many of the forum, I realize that a one day trip is not advised, (due to time needed for visit, cost effectiveness, etc.), however, for this trip, that is all we have. I told my father we can return to France in the future and stay in the Normandy region and do more in depth touring, but he seems to think this could be his one and only trip to France. I've read the various links and tour info. The linkParis tour seems to be the easiest, (as far as having all the planning "taking care of"), however, it is quite expensive, (~$300 American pp). There would be 4 of us in the group: my father, his wife, my 18 year old daughter and myself. I have been to Paris several times as a teacher leading student tours, but our "day trips" only involved an hour or so outside of Paris, (and all the planning was done by the tour company). For this trip, I am doing all the planning, (and frankly, it is a bit intimidating)! We are staying a week in London, (renting an apartment), then taking the Eurostar to Paris, for our weeklong stay in Vincennes, (timeshare exchange). Is there any advice/help you could offer re: DDay tour from Paris? Is the linkParis tour our best choice, or another option? Or is this a trip that should be saved for (hopefully) a return visit to France? Thank you so much for your help.
