Any suggestions on good child-centered tour guides for Paris for 8 and 10 year olds??
If you don't get a satisfactory response, rephrase it to say "what can I show my kids. . . .' and you'll have suggestions coming out your ears. I just pulled it off with a couple of much younger grandkids based loosely on what I'd shown my kids when they were about the age of yours. No complaints from either generation - - a few raised eyebrows when the shrimps ratted me out.
I'd recommend a HO/HO bus. My kids really enjoyed it, and it cut down on the amount of walking we had to do. Also recommend a Seine River cruise. Paris seems to be much more of a DIY city. There don't seem to be nearly as many guided tours as you find in other places.
