with our friends and their kids of the same ages...and they didn't really appreciate the big sites. We probably did too much museum and historical site stuff. So, there are a couple of companies the run hop-on-hop-off double-decker busses that take you too/past all the big sites in the city. You can get on and off a your leisure and you'll see a lot of the city. Not something I'd normal do, but when the kids started complaining we hopped on one and spent the second half of a day touring the city that way Worked out. Saw lots. The most memorable thing we did on a whim (on someone's recommendation) was visit a street called the Rue du Martyr (near Gare du Nord), which is a relatively short street lined with shops for locals. We spent a couple hours one morning walking, buying and tasting. Found some great stuff. Buy fruit! Incredible fruit. I'd personally skip Disneyland, but there maybe reasons that you don't. We also found a hole-in-the-way crepe stand and grab a bunch of crepes at 1:00am. Another fun memory. Enjoy!
