Paris?

I'm mad.  Mother Nature didn't get my letter because blogger erased it, and now it's raining again.  It makes me want to crawl in bed, so instead I'm focusing on our trip to France in the fall.  If any of you read Golda and Ruby's blogs, you know Coco and Bill are taking them (and me!!) to Paris.  They've been saving up so they don't have to scrimp on pastries and souvenirs.  this morning, Coco and I made a list of all the things we might want to see while we're there.  Coco is a hard-core Francophile, so she knows everything.  I lived there, in a little maid's quarters in Neuilly, when I was 14, for a couple of months.  I explored every inch of the city by hopping off the Metro at random stops and walking around.  Scott can't imagine our girls doing that on their own, but I thought it was wonderfully liberating and educational.  Coco made me promise I wouldn't turn my girls loose and see if they come back in one piece, however.  They will have adult supervision!

What I'm wondering is if any of you have favorite spots, activities, must-see destinations in the City of Light.  There are a thousand little cafes to discover and so many good museums and restaurants.  What would you do if you were taking young girls there for the first time?
