It’s always worth looking at what regular tickets would cost, instead of a pass.  And don’t forget to add in the cost of Eurail reservations - particularly within and to/ from France.

But yes, a 10 day in 1 month pass could work well.

Feel free to post your rough itinerary for more specific advice.

Very much appreciate your reply. I did not price out the individual trips as not all are determined yet. But also appreciate that value the pass provides in flexibility.

Will be arriving at AMS 31-Jul and will need to go to Rotterdam. The cruise is 7 days & will be in Rotterdam 5 days post cruise. Plan on a day trip to Arnhem in that time.

Next stop Berlin. For 1 week. No rail plans during that time as of now. 

To Cologne 4 days. Planning a day trip to another city along the Rhine tbd. 

Then to Strasbourg for 4 days, details tbd.

Then to Bayeux for a week. Expect to use train to visit the Overlord sites.

Lastly to Paris. Primarily to visit Notre Dame as it was closed when there in '22. Departing CDG to JFK 2-Sept.

Thankful for any feedback or suggestions.

Yes, I think with those long-ish journeys, a pass will be good value - especially if you value flexibility.

It’s just a question of totting up the number days you think you’ll use.

Couple of suggestions: 

There’s a scenic route down the Rhine, between Cologne and Mainz via Koblenz. Well worth the slightly slower journey, even if the panorama car has now been withdrawn.

From Netherlands to Berlin, you have the choice of day trains or a sleeper.
