Angelo:
My wife & I visited the D-Day invasion region last September, staying in Asnelles (east of Arromanches) for four nights.
The Invasion covered about 50 miles of coastline, so it would take quite a bit of time to see everything. This would be very difficult on a limited schedule. The American invasion landing areas alone (Omaha and Utah beaches) are about a 45-minute drive from each other. For that reason, I’d recommend choosing one landing area (Omaha, which is closest to Bayeaux?), and then selecting a guide who offers a tour of it.
I’d also suggest doing some reading in advance to get an appreciation of what occurred on D-Day. This will make your visit more meaningful (IMO, that is.) Warning you that I am a military history buff, Messenger’s “D-Day Atlas” gives a good explanation of the Campaign … with lots of maps.
For our trip, we drove ourselves to many of the landing sectors. Having a GPS programmed with French maps helped guide us. But I knew beforehand where I wanted to visit.
