Does anyone have any recommendations for a Paris day tour? I'm taking my daughter in mid-February and altough I've been several times, I thought it a good idea to take a brief day tour to give her an overview of the sights.

I've looked at a couple of websites, and they seem awfully expensive (over 100 E per person) for what you get (just a bus tour for a few hours). I'm also looking at hiring a private guide for an afternoon or morning - those are real expensive, but probably comparable when I add it up.

In terms of private guides, has anyone ever heard of someone named Michael Osman? his name has come up on some sites as a reasonably-priced guide for a simple tour.

Any ideas/suggestions would be most appreciated!
