Take the Kids Paris and Disneyland Resort Paris

This was really a very good guide book. The maps and pictures were really well done, and the book was comprehensive in its treatment yet very concise and portable. Very nicely done, even had a fairly good section on Disney Paris, although inevitably some things weren't as much detail as I would have liked (seasonal closing of some rides, details about hotels, etc). I really liked the themed itineraries at the beginning and really thought this was a nicely done book. For families with smaller kids, I recommend the first 2 "Madeline" books as well, and "Linnea in Monet's Garden" as ways to get the kids excited about Paris, and you can always throw in Disney's Hunchback video too. Remember to make reservations for the restaurant in advance, not only will you not get a seat otherwise, but you can avoid the long lines by going directly to the restaurant entrance.
