Brush up on French......though after several champagne tastings you are, of course, fluent! Sorry, I don't mean to be fascetious . Although I have had many, many trips to France, I have never stayed in this area, though have passed through. With an open mind, I am sure they will have a great time, but some French, even basics of s'il vous plait and merci (please and thank you - I am certain you know) will be appreciated.
