You can find specific responses on the Normandy Forum or the Paris Forum on Trip Advisor if you can't find enough responses here. June 6th in Normandy around the D Day beaches is always very busy and tours might be booked up well in advance. You can use the search function on TA and you will find many choices. I couldn't find anything on Victorytours on a brief search. Overlordtour.com, Dale Booth -- dboothnormandytours.com -- are but two of many tour operators from Paris to the D Day beaches, assuming you want a tour to the D Day beaches and not a general tour of Normandy. Staying a night or two in Bayeux is preferable and there is a Bayeux forum on TA. Good luck.
