Our party of 7 has located a wonderful private guide for Normandy/D-Day Beaches. He is a military historian, and charges 450Euros/day. We would like to find someone similar for a couple of days seeing chateaux in the Loire valley. We will have our own cars, so do not want to pay the premium for being driven around in a mini-bus. Can anyone recommend an English-speaking guide who is knowledgeable about history and architecture/decorative arts? Thanks!
