Hi
I've been across to Normandy several times around the 6th June again more by chance than design, took my father ( Normandy veteran ) to the 60th celebrations in 2004.
Well worth going, quite a few veterans attend, good atmosphere
Also quite a few WW2 vehicles, motorbikes in evidence
Try Bayeaux CWWG and memorial for possible organised remembrance service.
Also try contacting/websearch British legion/Remembrance Travel/Leger Coaches to see if there are any services/events, being organised this year before making your own arrangements.
4/7th Dragoon Guards Association ( Creully Club ) always hold a small remembrance service at their memorial in Cruelly on the 6th June each year.
Hope this helps
