Beware of wildcat strikes ruining your agenda. The Louvre was closed when I was there. So were the Eiffel Tower and most things. The metro was running tho (and it's free if you hop over the turnstile as many parisians did), cathedrals were still open and so was Versailles
Western Europe was great but I've more enjoyed my travels in Africa and East Asia because they were more interesting, exotic, and cheaper (except Japan). Next I think I'd like to try India.
Perhaps surprisingly, my favorite part of Western Europe so far has been rural England (but I sure haven't been everywhere in western europe)
But all my memories are fond ones!. So where ever you go and however you go, I'm sure it'll be a wonderful time!
