Thanks for the comments on my website. The museum in Overloon is stunning. You could spend a full day there.
As for Normandy, the highlights of my trip were Pegasus,
St. Mére-Eglise and Bayeux, but all of it was excellent. I had a brilliant and moving time. You can't go wrong.
As for written itineries, we had the Holts Battlefield Guide with us and used it as a tool to plan the trip beforehand. They have suggested tours in them timed for the motorist, but we made our own up. Here's a link to it:

They do a wide range of other sites as well.
Sapper, I'm sure you've had it said before, but I feel I must say it again.
Thanks for yours and your mates sacrifices. I treasure my freedom.
