We found the Paris Pass very helpful since it was our first time there this past July. The "hop-on-hop off" bus allowed us to get our bearing, and see quite a lot of different things in a short period of time. We used it alot. I would recommend it for those who haven't been to Paris before. It gave us a good starting point for the trip.i.e. what to see etc.
I would order the book BEFORE you depart, as some places i.e. the wine tasting need to have a reservation in place before you go there. Therefore familiarize yourself with what you would like to see and do, so you don't miss out. Several people were turned away from the wine tasting because they did not call and reserve before showing up.
