We've been 'doing' France for 26 years, twice (or more) a year, and haven't yet run out of ideas. We have been back several times to areas that we love, but each year make a point of trying somewhere new - and every year we've enjoyed our holidays. We haven't yet touched the Vendee or southern Brittany.
We've also done Luxembourg, Belgium, Germany, Holland, Spain, and Italy - and are now thinking of going back to Czechoslovakia - somewhere we visited in the 1970's - and would love to see how it's changed!! Then there's Poland, Hungary, Estonia, Latvia, Lithuania, Portugal, Moroccco - Europe is your oyster - just go for it!!!
