Well, your options in Europe are:
France (of course)
Monaco (French & Italian spoken)
Corsica (the island)
Switzerland (one part is deemed French but most Swiss speak all of the languages spoken in Switzerland)
Anyone think I forgot someplace? So do any of those places interest you?
I think Belgium, especially Bruges, might be particularly charming at Christmas, ditto for a little French hamlet in French Switzerland. Switzerland just oozes the warm fuzzies for me round that time, I dunno.......
I LOVE Paris and it's so pretty when decorated but they start decorating it in November and so I've seen that. You'd maybe want to be somewhere in the Alps for Christmas I think.
Anything tickle your fancy?
